Strongest interferer adaptive single-user receivers in cellular radio environments

In order to achieve a high capacity in cellular radio systems, modulation techniques and receivers have to be resistant to interference from other users. One method to achieve this involves interference adaptive receivers. In this paper we study the performance in symmetrical cellular systems of strongest interferer adaptive single-user receiver schemes. Performance evaluation demonstrates that by applying these receivers, the downlink cell average error probability is reduced. Consequently, the system capacity is enhanced compared to a system with conventional receivers. Results show that by using the adaptive receiver schemes a cluster size reduction of one step is achievable for hexagonal cell layouts. For base stations on a symmetrical grid, the performance gains in the downlink are shown to be almost independent of the cluster size and of the base station activities.
