Abstract :
In this paper, we propose to combine space-time block codes (ST-BC) with multiple input multiple output equalizer (MIMO-EQ) for achieving transmit diversity in a frequency selective Rayleigh fading channel. In the proposed system, MIMO-EQ equalizes the channel into a temporal intersymbol interference (ISI)-free channel, and then a simple linear processing is used to perform the maximum likelihood (ML) decoding for ST-BC. Our simulation results show that the proposed system can achieve the full spatial diversity gain
