摘要：
In this paper, new transmission schemes are proposed to deal with the CCI (co-channel interference) in wireless relay transmission. We first introduce an optimal decoding process to fully utilize the information forwarded by relay. Then based on conventional transmission schemes, two modified transmission schemes and a novel adaptive scheme are proposed. Furthermore, we derive the outage probabilities and throughput for all the proposed schemes in closed form. Numerical simulations are presented to validate the analytical results and it shows that the adaptive scheme improves the spectral efficiency significantly compared to others in most condition.
