Rate Regions of Asymmetrical Multiple Access with Receive Diversity
— Based on the specification of a high-throughput wireless local area network system we consider the achievable rate regions of time, frequency and code division multiple accessing schemes. We are especially interested in how the schemes compare if the receiver has multiple antennas. Our results show that given a fixed total number of transmitting antennas putting more antennas at the receiver helps tremendously in separating simultaneously transmitting users. Then the individual rates at which the users can transmit simultaneously are increased and code division (CDMA) becomes increasingly attractive over the other two. We focus on the case in which the transmitters do not know the channel but the receiver does. Then the preferred successive decoding and interference cancellation CDMA receiver is suboptimal. However, code division still performs best.
