本研究課題は、時間・周波数同期誤差が誘発する干渉成分を効率的に抑圧するBP検出法の確立とその理論限界の解明を目的としている。効率的な干渉抑圧のために、非同期に起因して散乱する信号成分をかき集める構造としてOTFS (Orthogonal Time Frequency and Space)変調の構造が有効であると判断し、OFDMの代わりにこれを利用する。2021年度は下記の2課題のサブテーマを実施した。 [課題1] 非同期ランダムアクセスのためのBP 検出器の開発 -(a)「非直交OTFS復調器」 [課題2] 深層展開型BP 検出器のデータ駆動設計 - (a)「通信路復号器」 [課題1]-(a)では、通信路状態が完全に推定されているという理想的な前提で、BP検出器に適応スケールを導入することで非同期OTFSの信号検出精度が高まることをBER特性の観点から明らかにした。また、大規模マルチユーザMIMO検出のための信念伝搬法と深層学習の融合に関しての基礎検討も多数行い、その研究成果を報告した。特に、双線形推論に基づくベイジアン受信機に関する検討は、2022年度に実施予定である[課題1]-(ｂ)セミブラインド通信路推定にて有効利用することができ、多くの知見を見出すことができた。 [課題2]-(a)では、短符号長の巡回冗長検査（CRC）符号を誤り訂正符号として用いる場合に、BP復号器が受ける外れ値の影響を緩和する方策として、深層展開型深層ニューラルネットワーク構造を設計し、データ駆動最適化の効果を明らかにした。また、ブラインド通信路推定を前提とした独立成分分析に対してデータ駆動最適化を施し、その有効性を確認した。, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2021/04 -2025/03, Principal investigator, Grant-in-Aid for Scientific Research (B), Doshisha University - A Study on Software Defined Radio over Fiber for Wireless Access Networks
Saruwatari Shunsuke
Future networks will require network technologies that combine high capacity, low latency, and flexibility to enable many services that require higher quality wireless networks, such as teleoperation of automobiles and tele-surgery. To address these requirements, this research has realized SD-RoF (Software-Defined Radio over Fiber), an architecture that tightly couples optical and wireless at low cost. SD-RoF is a combination of elastic wireless services and elastic bidirectional passthrough. In this study, the design and implementation of SD-RoF were prototyped and validated., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2018/04 -2022/03, Coinvestigator, Grant-in-Aid for Scientific Research (B), Osaka University - Detection of Large Scale and Overloaded Signals from Massive IoT devices Based on Belief Propagation
Ohgane Takeo
For accommodating massive IoT devices in a common channel, we developed methods which can correctly detect all of the signals with much fewer observations and much lower complexity. We newly proposed convex optimization with ADMM based on discreteness and group sparseness and improved Gaussian belief propagation and approximate message passing with parameter optimization using deep unfolding. Consequently, we succeeded to establish light-weight and high-performance signal detectors., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), 2018/04 -2021/03, Coinvestigator, Grant-in-Aid for Scientific Research (A), Hokkaido University - Statistical iterative indoor positioning based on turbo principle
Ibi Shinsuke
In this project, we aimed to establish a statistical signal processing method that comprehensively estimates the results of indoor positioning by means of BLE (Bluetooth Low Energy) fingerprint and surveillance camera as prior knowledge for each other. Indoor experiments using a transceiver equipped with commercially available BLE dongles were conducted. As a result, we clarified that it is possible to improve the estimation accuracy by the statistical signal processing. Also, we confirmed the validity of the proposed unified position estimation method that compensates for each other's drawbacks by the advantages of camera images and wireless beacons., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), 2016/04 -2019/03, Principal investigator, Grant-in-Aid for Scientific Research (C), Osaka University - Analysis of a large-scale bipartite factor graph with analog coupling
Takeo Ohgane
It is known that we can obtain the global solution of a complex problem by decomposing it into multiple sub-problems and solving the small problems with exchanging the partial solution (reliability information) among them. The correct solution may not be obtained when some reliability exchange loops exist. However, an exception, i.e., an appropriate convergence can be seen if the problem size is very large. In this project, we tried many tests under various situations and obtained the fact that the effect of incorrect reliability propagation decreases with the problem size. From this results, we have succeeded developing a method adjusting the reliability information. In addition, the validity of the obtained method has been confirmed by another optimization approach., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), 2015/04 -2018/03, Coinvestigator, Grant-in-Aid for Scientific Research (A), Hokkaido University - Decentralized and Scalable Wireless Connection for Control Systems using Wireless Distributed Networks
SAMPEI SEIICHI
This project aims to develop technologies for connecting vertical sectors to wireless distributed network (WDN) based networks, thereby achieving flexible and scalable vertical sector connections, where vertical sector means control systems, transport systems and so on that are not currently connected to information and communication technology networks. Specifically, this project consists of the following 6 part, improvement of wireless link level performances, performance improvements of layered mesh networks using MIMO based bi-directional flows and network coding, as well as distributed control based inter-layer resource control, development of game theory and machine learning based distibuted control techniques, wireless resource management between adjacent-networks, and development of experimental electrical light networks to evaluate a part of developed technologies., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), 2012/04 -2017/03, Coinvestigator, Grant-in-Aid for Scientific Research (A), Osaka University - A Study on Suppression of Self-Noise Propagation in Iterative Detection of Unified Channel Estimation, Synchronization, and Decoding
Shinsuke Ibi
In this project, after regarding various cutting-edge wireless communication technology as functional modules, unhealthy harmonization among the modules was removed from a viewpoint of EXIT chart analysis with the aid of iterative detections. The iterative detection was applied to several scenarios: (1) iterative channel estimation, (2) blind detection of virtual differentially coded systems, (3)Massive MIMO detection, (4) Independent component analysis of BLE signals, and (5) iterative detection between GFSK and CRC. Computer simulations validated the proposed application in terms of enhancements of system capability., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), 2013/04 -2016/03, Principal investigator, Grant-in-Aid for Scientific Research (C), Osaka University - COnnect All by Turbo NETworks-2: Extension to Correlation Networks (COATNET-2)
MATSUMOTO Tadashi; KHOIRUL Anwar; MURATA Hidekazu; ISAKA Motohiko; IBI Shinsuke
The objectives COATNET-2 has, as an extension of its successor project, COATNET, and three work packages in the project: (1) Wireless Cooperative Communications, including Relaying, (2) Protocol and Scheduling Techniques Design for Distributed Wireless Network, and (3) Design of Practical Transmission Chain and Signal Processing Techniques. The targets of each Work Packages follow the major results of the successor project, COATNET, and the major aim of COATNET-2 is to identify how we can best utilize the information sequence correlation caused by the network. We finally found that the cooperative network, as a whole, can be seen as a distributed source-channel code where regardless of each link's transmission is lossless or lossy. By applying the framework of the lossless/lossy distributed source-channel coding theorem, it has been shown that the proposed network design and processing techniques can achieve much higher efficiency than the conventional techniques., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2011/04 -2014/03, Coinvestigator, Grant-in-Aid for Scientific Research (B), Japan Advanced Institute of Science and Technology - A Study on Digital-Analog Concatenated Coding and Iterative Decoding
IBI Shinsuke
In this research, several cutting-edge wireless communication techniques are regarded as modules which are classified into three types: digital codec, analog codec, and wireless channels. In order to approach the maximum capability of the triple concatenated systems, mismatch among the modules are removed as possible in terms of mutual information. A major contribution of this research is an approach that extrinsic information transfer (EXIT) characteristics plays a key role to remove the mismatch., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B), 2011 -2012, Principal investigator, Grant-in-Aid for Young Scientists (B), Osaka University - COnnect All by Turbo NETworks (COATNET)
MATSUMOTO Tadashi; MURATA Hidekazu; ISAKA Motohiko; IBI Shinsuke
The primary objectives of the COATNET project are fourfold : Optimal design of source/channel coding and signaling techniques, X-layer design optimization by the Turbo principle, Resource allocation based on the results of convergence property analysis of the mutual information exchange, and verification using field measurement data. A commonalty among those objectives is to identify the cause (=transmitted signals) of the observation (=received signals) through extrinsic information transfer (EXIT) analysis, and the final goal is to establish optimal design of distributed networks. We believe that those primary objectives have been achieved, as detailed in 4 : Achievement section., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2008 -2010, Coinvestigator, Grant-in-Aid for Scientific Research (B), Japan Advanced Institute of Science and Technology - Cluster Relay Coded Cooperative Transmission in Ad-Hoc Wireless Networks
IBI Shinsuke
In this research, a concept of cluster relay coded cooperation and its iterative detection scheme have been proposed. The concept is effective in forming secure network connections among wireless nodes without the aid of any centralized administration control even in highly mobile networks. In addition, the coded cooperation has been extended to enhance its code structure by adopting exclusive OR operation at relay nodes., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B), 2008 -2009, Principal investigator, Grant-in-Aid for Young Scientists (B), Osaka University
