Session Title:
Analog Circuits and Their Applications

Organizer:
Fujihiko Matsumoto (National Defense Academy, Japan), Hao San (Tokyo City University, Japan), Nicodimus Retdian (Shibaura Institute of Technology, Japan)

Session Abstract:
The rapid progress of IoT (Internet of Things) demands the evolution of integrated circuits in many fields such as information system, communication system, health/biomedicine, and energy management. Recent analog circuits and its integration technologies have made a great contribution in these fields. Challenges toward enhanced functionality as well as excellent performance of analog circuits, while keeping low power and low cost, are strongly demanded for the next generation applications. In addition to pure analog circuit techniques, the scope of this special section includes fundamental issues such as co-design of analog and digital circuits, analog circuits in System-on-Chip (SoC) environments, analog circuit design for manufacturability (DFM) and testability (DFT), as well as device modeling technologies.

Session Title:
Recent Advances in Nonlinear Image and Signal Processing

Organizer:
Mitsuji Muneyasu (Kansai University, Japan)

Session Abstract:
Nonlinear signal and image processing theory has a long history, and various applications have been proposed. On the other hand, the recent development of statistical learning theory and deep learning has also greatly affected signal processing technology. In addition, from the viewpoint of large-scale data processing, the use of GPUs and hardware realization are attracting attention. In particular, since deep learning is a development of the neural network, it has the high relationship with nonlinear signal processing theory, and it has high relevance to GPU and hardware realization. Therefore, considering these recent trends, we would like to propose a special session aimed at compiling recent research on nonlinear signal and image processing. The scope of this special session is signal and image processing theory by nonlinear model, its hardware realization, its application, and others demonstrated to provide an excellent performance of speech enhancement. A new measurement for the quality of speech obtained by speech enhancement is also derived. For speech analysis, pitch detection in noise is discussed from a new framework to utilize sparse linear prediction. Each presentation will be conducted by an expert in the field of acoustics and speech processing. Totally, this session will consist of six presentations.

Session Title:
Speech Processing in Noisy Environments

Organizer:
Tetsuya Shimamura (Saitama University, Japan)

Session Abstract:
Recently, great deals of attention have been paid to strategies against noise in the field of acoustics and speech processing. In this session, a new concept for active noise control system is derived with a fast tracking adaptive algorithm. Also, a measurement technique for acoustic impulse response in noisy environments is found, which is an extended version of blind system identification. Speech analysis and enhancement are discussed utilizing bone-conducted speech, a recent hot topic, as well as air-conducted speech. Support of bone-conducted speech improves the performance of speech enhancement in highly noisy environments. For a widely used rage of noise level, non-local means, an image denoising technique, is applied to noisy speech and

Session Title:
Signal Processing for Multicarrier Transmission

Organizer:
Tetsuya Shimamura (Saitama University, Japan)

Session Abstract:
Multicarrier transmission is a key technology for current and future wireless communication systems. In this session, especially orthogonal frequency division multiplexing (OFDM), multicarrier- code division multiple access (CDMA) and single carrier - frequency division multiple access (FDMA) are dealt with. For OFDM systems, a multiuser (MU)-multiple-input multiple-output (MIMO) case is considered at first. A new technique to separate transmitted signals is derived and validated. For MIMO-OFDM based systems, RF modules are also developed, which especially focus on the realization of a video communication system. With those modules, more excellent performance than with standard ones is expected. There exist some exciting research topics such as cognitive radio and sensor network. As one technology of cognitive radio systems, spectrum sensing is discussed in this session. An efficient and effective method in parallel structure is found and discussed. For sensor networks, a CDMA system with multi-carriers is considered and targeted to an on-demand system. Sensor nodes are discussed from several aspects including lifetime and robustness against co-channel interference. On the other hand, frequency division multiple access (FDMA) with single carrier is improved to combat phase noise and deep fading effects, where an iterative approach is effectively employed, resulting in mitigating both the effects simultaneously. Each speaker is an expert in the field of wireless communication systems, and this session will significantly contribute a realization of future wireless communication systems from aspects of software and hardware engineering.

Session Title:
Recent Advances in Wireless Signal Processing

Organizer:
Fumiaki Maehara (Waseda University, Japan)

Session Abstract:
Wireless data and Internet services exponentially increase mobile traffic, and its trend will continue in future due to extending the range of usage scenes. The next generation mobile system (5G) mobile system of which services are planning to start in 2020 covers wide variety of services including internet-of-things(IoT), intelligent transport systems (ITS), healthcare, education, and so on. Therefore, 5G is expected to play a key role as social and industrial infrastructure. In order to design such a network, ultra-high throughput, huge number of connectivity, and ultra-low latency are needed to be simultaneously achieved, which motivates us to further sophisticate technologies in the area of signal processing. The main goal of this special session is to explore the new ideas in the area of signal processing for the research and development of the 5G and beyond, and capture its current advancement. Especially, this session provides the recent results related to space signal processing including massive MIMO, user scheduling, NOMA as the invited talks.
