Abstract :
In this paper, we extend the 3GPP transmit diversity system by increasing the number of antenna elements from 2 to 4, to improve the BER performance. The increase of feedback signal message bits is kept low. The effect of spacing distance between antennas, control delay time and the maximum Doppler frequency on BER performance is studied under flat fading and frequency-selective fading.
