Novel hybrid receiver for interference cancellation and suppression in sidehaul system

Recently, the 3rd Generation Partnership Project (3GPP) has developed a sidehaul system to cope with the explosively increasing mobile data traffic. Nevertheless, numerous challenging technical problems that need to be overcome remain. One of the major problems is interference management between small cells. In this paper, we propose a novel hybrid receiver for full successive cancellation (FSC) to reduce the interference from neighboring cells in the sidehaul system. The proposed receiver can cancel and suppress interference by integrating the interference rejection combining (IRC) technique with successive interference cancellation (SIC). We perform a simulation based on the 20-MHz bandwidth of the 3GPP LTE-Advanced technology. Simulation results show that the proposed receiver can achieve a lower error rate and a higher throughput compared to conventional receivers.
