Abstract

In this paper, firstly we briefly introduce several exiting MIMO-OFDM systems. We take a new look at a coding and decoding algorithm of the STBC-OFDM system by applying it to the space-frequency coding (SFC) OFDM system. The SFC-OFDM system can achieve not only space diversity gain but also frequency diversity. Simulation results show that in a multi-path fading environment, the performance of the SFC-OFDM system proposed in this paper is rapidly improved over signal OFDM systems. The complexity of the proposed algorithm is lower than that of the other existing SFC-OFDM systems.
