| Abstract(in English) | Beamforming using SVD-MIMO suppresses signal interference among antennas, and improves MIMO communication quality. In this paper, we describe a hardware design of singular value decomposition processor for SVD-MIMO systems dealing with maximum 16 transmission antennas, and report evaluation. The proposed processor based on ASIP(Application Specific Instruction-set Processor) architecture. We optimize the algorithm by determining the minimum number of QR method iterations by the simulations according to the MIMO configurations, and make efficient by using 4 floating-point units and some dedicated instructions specialized in norm computations. In the result, the circuit area was 27 kgates, the maximum clock frequency was 400 MHz, and the maximum power consumption was 17.5 mW. |
