With the increase in the number of MIMO streams and OFDM subcarriers for high-speed wireless communication, the amount of computation required for signal separation is rapidly increasing. In representative method of signal separation, such as MMSE, ZF and SIC, the implementation of matrix inversion has a great impact on processing time and bit error rate. This paper studies a pipelined hardware design of matrix inversion based on Strassen algorithm and floating-point number arithmetic. The results of logic synthesis and simulation show that the throughput can be improved efficiently against the increase of the circuit resources induced by pipelining. |
