Mr. Ikeshita presented his paper at 2016 Joint Convention, the Hokkaido Chapters of the Institutes of Electrical and Information Engineers, which was held at Hokkai-Gakuen University on Nov. 5th-6th. In this paper, we reduced the amount of memory and operation of an FPU-based matrix inversion circuit for MIMO-OFDM demodulation. The circuit has the scalability in the target matrix size and the number of FPUs. This paper evaluated the circuit area and the processing cycle count.

A student exchange meeting was held during this workshop. Students of each university made presentations about their university, research activity, and student activity. Mr. Uesaka who is the chair of IEEE student branch at Hokkaido university introduced the activity of the student branch.
On Oct. 16, IEICE Hokkaido Section Special Workshop was held at Lecture Hall, Frontier Research in Applied Sciences Building, Hokkaido University. The workshop topic is next generation video wireless communication networks, where the chair is Prof. Miyanaga. Associate Professor Tsutsui gave a lecture at this workshop as one of lecturer.
Mr. Umehara presented our research achievements at Smart Info-media Systems (SIS) Technical Committee (TC) Conference held in Hokkaido University Centennial Hall on 10th July. This TC Conference was cosponsored by SIS-TC and TCs from System and Signal Processing Sub-Society (SSP) which includes Circuits and Systems (CAS), VLSI Design Technologies (VLD), Signal Processing (SIP), and Mathematical Systems Science and Its Applications (MSS). Assoc. Prof. Tsutsui served as one of local organizers.
