Abstract

In this paper, the performance of the two transmit diversity schemes with four antennas proposed in [6] is analyzed by simulation. It is shown that the first scheme outperforms the second one. In addition, we also investigate the effect of the estimate error of the channel gains on the system performance. As an alternative, we consider the pilot signal assisted channel estimate scheme. By simulation, some results on the length of the pilot signal are presented according to the requirement of the quality of service (QOS) in practice.
