In this thesis, we propose using iterative multi-user detectors for co-channel interference (CCI) suppression in wireless cellular systems. We demonstrate that a receiver with a single receive antenna is capable of detecting and cancelling a single in-band interferer that uses the same coding and modulation scheme as the desired signal. We investigate the benefits of using such an interference canceller in the mobile unit receiver in the downlink scenario of single-hop as well as two-hop networks. Results show significant improvements from iterative interference cancellation in terms of the average system throughput and outage probability. Benefits also include enabling the use of 3-sectored cells, where all sectors share the same frequency band, and the use of non-orthogonal channels for relaying. |
