Performance of Pico-Cell Clusters with Cooperative Receivers
Pico-cell clusters have been proposed for providing high capacities to dense sets of users in next generation networks. The authors consider the uplink channel and analyze the sum-rate performance of two interfering pico-cell clusters with cooperative Multi-cell Joint Decoding (MJD). The performance of a linear receiver is compared with that of non-linear receivers which allow message passing between the clusters in order to cancel the associated interference. The receiver, in all the above cases, jointly processes all signals across a single cluster. However they consider different message passing schemes, and maximize the sum rate over system parameters, including the load in each cell.
