Abstract

In wireless communication, Multiple Input Multiple Output (MIMO) technology has proven to improve reliability through spatial diversity. Cooperative relay transmission is an emerging concept, which involves the users to share their resources to improve overall system performance. In this work, Selective Decode and Forward (SDF) cooperative relaying scheme is analyzed. This paper describes power optimization in relay nodes for a dual hop half-duplex SDF based cooperative relay communication system, with nodes using multiple antenna. For the proposed system model, average end-to-end probability of error is derived, leading to evaluation of asymptotically tight upper bound under high signal to noise ratio. Optimal power allocation to minimize the bit error rate (BER) is formulated and a closed form solution for this convex optimization problem is derived and verified through simulation. The BER performance of the system is compared with that of cooperative relay network having single antenna at the participating nodes. Results show sharp decline in error rate with increase in the number of participating antenna. Simulation results reveal that cooperate scheme with optimal power allocation has an improved performance, compared to its direct link counterpart.
