In this paper, we propose a VLSI design of a 4×4 MIMO-OFDMA down-link baseband receiver for the mobile communications. The receiver consists of synchronization, channel estimation/compensation, precode codebook search, and MIMO detection. To realize the closed-loop MIMO system in the mobile environment, we utilize the MMSE-OSIC algorithm for MIMO detector and capacity selection criterion for precode codebook searcher, in which the Strassen's algorithm is employed to reduce their matrix… CONTINUE READING
