Iterative suppression of Co-Channel Interference

Co-Channel Interference (CCI) is one of the major bottlenecks in the performance of today's densely planned wireless cellular systems. A receiver equipped with multiple receive antennas and sufficient computational budget typically exploits the spatial dimension and iterative processing between the detector and the channel decoder to suppress this interference. In this paper, we propose modifications in the standard iterative turbo processing based CCI suppression to especially boost the receiver performance in a dominant CCI scenario. Performance gains of 3-5 dB are shown to be achieved over the conventional iterative approaches for an LTE uplink system.
