Abstract :
Transmit diversity has been shown to be an efficient method to improve system performance without the increase of the mobile terminal complexity in wireless communications. The impact of propagation time difference between transmit antennas on the performance of a transmit diversity scheme has been studied under a Rayleigh fading channel. It has been shown that the performance of transmit diversity degrades significantly when the propagation time difference increases.
