Abstract :
This paper proposes beat interference suppression techniques for point to multi-point (P-MP) communication systems, where the multiple base stations (BSs) transmit the same information at the same frequency band. The proposed communication systems employ transmission time diversity at the transmitter and adaptive equalization at the receiver. Finally, computer simulation shows that the proposed techniques improve the BER performance under beat interference and fast time-varying fading environments
