- Abstract
- We examine the downlink of wireless communication systems with receiver cooperation. The cooperative utilization among closely-located receiver nodes is referred to as cooperative receiving, which behaviors similar to multiple-antenna receiving. To realize the “cooperative diversity,” a group of receiver nodes are first to form a cluster, which necessitates a node selection algorithm. The operation of such node selection is similar to antenna selection in multiple-input multiple-output (MIMO) systems, except that relaying (or cooperation) cost should be considered. We propose a few node selection algorithms appropriate for receiver cooperative downlink systems. Simulation results indicate that the performance of the node selection algorithms is significantly dependent on the distances among receiver nodes.
