Recently, space-time block coding has emerged as a promising spatial transmit diversity scheme, mainly due to its simple decoding complexity. As it was initially proposed, space-time block coding was based on the assumption of flat multipath fading channel, where there is no intersymbol interference. In this paper. we investigate the performance of two different receiver proposals using space-time block coding for frequency selective fading channels. The first one, called here equalization pos-combining with channel estimation receiver, is based on the time-reverse space-time block coding proposed by Lindskog and Paulraj and it performs channel-estimation, linear combination and equalisation. The second one, denoted here multiple-input multiple-output joint equalization-combining receiver, is based on the scheme presented by Meshkati and Sousa and it performs channel equalisation, interference cancellation and linear combination simultaneously. Simulation results show that, increasing the signal to noise ratio, multiple-input multiple-output joint equalisation-combining can outperform equalisation pos-combining with channel estimation.
