RESUMO

Multiple antenna wireless communication systems achieve high data transmission rates and good robustness to channel fading when signals traveling through the system are jointly processed in their transmitters and/ or receivers. In general, signal detection techniques assume perfect knowledge of the channel state information, in both transmitter and receiver, a hypothesis which is not always valid. In this sense, it is important to analyze is done by the comparison between the calculus of the probability of symbol error and the symbol error rate obtained by computer simulation for the zero-forcing detector, assuming the use of linear criteria detection and by applying the technique of successive interference cancellation
