2016 Joint Convention Record, the Hokkaido Chapters of the Institutes of Electrical and Information Engineers, Japan

Mr. Ikeshita presented his paper at Joint Convention Record, the Hokkaido Chapters of the Institutes of Electrical and Information Engineers, Japan, which was held at Hokkai-Gakuen University on Nov. 5th-6th. In this paper, we reduced the amount of memory and operation of a 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.
