Analysis of Equalization Pos-Combining with Channel Estimation and MIMO Joint Equalization- Combining Receivers for Space-Time Block Coding

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 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 equalization. The second one, denoted multiple-input multiple-output joint equalization-combining receiver, is based on the scheme presented by Meshkati and Sousa and it performs channel equalization, interference cancellation and linear combination simultaneously. One of the main simulation results shows that multiple-input multipleoutput joint equalization-combining receiver outperforms equalization pos-combining with channel estimation as signal to noise ratio increases.
