Abstract

In this paper, we consider multiuser cooperative multiplexing schemes in cellular networks with fixed relays and address the problem of inter-user interference. We propose two schemes to mitigate the effect of the interference: an interference cancellation scheme and a cooperative precoding scheme. The interference cancellation scheme utilizes the broadcast nature of the signal transmitted to the fixed relay, and is based on a decode- and-forward relaying protocol. The second scheme we propose is a cooperative precoding technique which employs a cooperative linear filter at the transmitter to eliminate interference. Simulation results show that both proposed schemes enhance the achievable throughput significantly.
