Title: Low complexity power allocation in multiple-antenna relay networks
Abstract: In this paper we study a two-hop cooperative communication system to enhance system coverage and data rates for the uplink in a cellular network. The throughput maximization is formulated into a convex optimization problem. A suboptimal numerical algorithm to approach the maximum sum capacity based on the decode and forward scheme is proposed and the numerical algorithm has an iterative implementation with fast convergence. The performance is close to the min-cut max flow (MCMF) bound. The proposed scheme is compared with two other cooperative schemes and shows significant performance gain.
