講演タイトル: AI-Assisted Reconfigurable Intelligent Surfaces (RIS) Wireless Networks
※講演は英語で行われ通訳はつきません
講演概要： In this talk, we will present some recent results on the reconfigurable intelligent surfaces (RIS) wireless network empowered by AI, in particular a deep-learning-based hybrid beamforming for RIS-empowered multi-hop teraherz communications, AI-assisted MAC, and intelligent spectrum learning with RIS. Such AI-based solution is particular of important when the network involves multiple users, as the signals impinging upon an RIS can be contaminated by interfering signals which are usually dynamic and unknown. To address this issue, ‘learning’ the properties of the surrounding spectral environment is a promising solution. Motivated by the convergence of artificial intelligence and spectrum sensing, we termed here as spectrum learning, where the RIS controller becomes capable of intelligently ‘think-and-decide’ whether to reflect or not the incident signals.

Dr. Tadashi Matsumoto
講演タイトル：
Recent Results in Advanced Wireless Cooperative Communications
講演概要：
Network Information Theory is an extension of Shannon’s Information Theory to Networks. We have thought that the key to the successful development of new mobile wireless communications system concept should be to utilize the latest results of Network Information Theory in the most suitable forms, which satisfy network objectives and requirements in efficient way. Also, identifying the theoretical performance limit is of most crucial importance. Under such significant and ambitious goals and objectives, he has worked for almost 40 years including experiences in the industry (NTT/NTT DoCoMo), Center for Wireless Communications (University of Oulu, Finland), and JAIST. Recently, he has been intensively researching how Lossy Distributed Multi-terminal Source Coding Theory, with the aim of how the theoretical framework should be modified so that it can be best-suited to mobile wireless cooperative communications systems having massive wireless devices. He also has considered how Network Information Theory should be understood in the design of wireless mesh networks, relay communications, sensor networks, Internet-of-Things (IoT) and Vehicle-to-Things (V2X) networks. His challenge has included theoretical limit analysis, algorithm design, and verification by simulations.
The reason for the pursuance towards the goals described above is that in IoT, V2X, and Edge computing, the lossless recovery of information observed by the sensing devices should not necessarily be End-to-End Lossless. In other words, the purpose of IoT network is NOT the full recovery of observations, but to make correct decisions based on the observations made by massive sensing devices which are assumed to be distributed around the target, and hence the corrected information is correlated. By utilizing the source correlation knowledge at the receiver, Ultra Reliable Low Latency Communication (URLLC) is possible, even though packet-wise transmission is lossy.
In the Seminar, also the recent results of his research group are introduced, which covers performance analysis of Lossless/Lossy Multi-source transmission over fading Multiple Access Channels, such as Wyner Ziv systems over fading MAC.
At the final stage, his future view of the research trends, one of which, he thinks, is towards creation of the theoretical framework for Distributed Hypothesis Testing, will be briefly introduced.

講演タイトル
Wireless powered edge computing
※講演は英語で行われ通訳はつきません
講演概要：
Finite battery lifetime and low computing capability of wireless devices (WD) have been longstanding performance limitations of many low-power wireless networks, e.g., wireless sensor networks and Internet of Things. The recent development of wireless power transfer (WPT) and mobile edge computing (MEC) technologies provide promising solutions to fully remove these limitations so as to achieve sustainable device operation and enhanced computational capability. In this talk, we consider a multi-user MEC network powered by WPT, where each energy-harvesting WD follows a binary computation offloading policy, i.e., data set of a task has to be executed as a whole either locally or remotely at the MEC server via task offloading. In particular, we are interested in maximizing the sum computation rate of all the WDs in the network by jointly optimizing the individual computing mode selection and the system transmission time allocation. Both model-based optimization and deep learning based methods will be discussed.

Optimum designs of Wireless Networks with Massively Distributed Antennas and Non-ideal Optical Front-hauls
※講演は英語で行われ通訳はつきません
講演概要：
Employing massively distributed antennas brings radio access points (RAPs) closer to users, thus enables aggressive spectrum reuse that can bridge the gap between the scarce spectrum resource and extremely high connection densities in future wireless systems. Examples include cloud radio access network (C-RAN), ultra-dense network (UDN), and cell-free massive MIMO system. These systems are usually designed in the form of fiber-wireless communications (FWC), where the distributed antennas or RAPs are connected to a central unit (CU) through optical front-hauls. The large number of densely deployed antennas or RAPs requires an extensive infrastructure of optical front-hauls. Consequently, the cost, complexity, and power consumption of the network of optical front-hauls may dominate the performance of the entire system. This talk provides an overview and outlook on the architecture, modeling, design and performance of FWC systems with massively distributed antennas. The complex interactions between optical front-hauls and wireless access links require optimum designs across the optical and wireless domains by jointly exploiting their unique characteristics. It is demonstrated that FWC systems with analog radio-frequency-over-fiber (RFoF) links outperforms its baseband-over-fiber (BBoF) or intermediate-frequency-over-fiber (IFoF) counterparts for systems with shorter fiber length, lower transmission power, and more RAPs, which are all desired properties for future wireless communication systems.

Collimated light propagation: The next frontier in underwater wireless communication
※講演は英語で行われ通訳はつきません
講演概要：
Traditional underwater communication systems rely on acoustic modems due their reliability and long range. However their limited data rates, lead to the exploration of alternative techniques. In this talk, we briefly go over the potential offered by underwater wireless optical communication systems. We then summarizes some of the underwater channel challenges going from severe absorption and scattering that need to be surpassed before such kind of systems can be deployed in practice. We finally present some of the on-going research directions in the area of underwater wireless optical communication systems in order to (i) better characterize and model the underwater optical channel and (ii) design, develop, and test experimentally new suitable modulation and coding techniques suitable for this environment.
