In order to improve system achievable rate and throughput for wireless systems, this paper proposes a cooperative relay transmission scheme with interference cancelation. By overhearing interference signal as a priori information, the proposed scheme uses interference reconstruction and subtraction to cancel interference,reducing the time slot. Moreover, the paper derives the system achievable rate and outage probability expressions, and analyses the performance of different transmission schemes in diverse relay modes. Simulation results show that the proposed scheme can effectively improve the system achievable rate as the link signal-tonoise ratio (SNR) increases. By adjusting the transmission rate, optimal system throughput is obtained when
the link SNR at the receiver is unknown.
