Abstract(in English) | In this paper, we propose a processor for singular value decomposition (SVD) and compression/reconstruction of feedback matrix, which is mandatory for SVD - multiple-input multiple-output - orthogonal frequency division multiplexing(MIMO-OFDM) systems. The SVD-MIMO is a transmission method, which can suppress multi-stream interference and improve communication quality by beamforming. Because of high calculation cost, any conventional SVD processors are unsuitable for real-time processing. We have employed an application specific instruction-set processor(ASIP) architecture and have realized the high-speed/low-power design and realtime processing by the parallelization of floating point unit(FPU) and arithmetic instructions specialized in complex matrix operations. |
