| Abstract | ||||
| In this paper, an adaptive protocol to enhance the performance of cooperative wireless communications based on a smart antenna system for a Uniform Circular Array (UCA) using Particle Swarm Optimization (PSO) technique is presented. The results are compared with those obtained using Uniform Linear Array (ULA). In addition, the best strategy for transmission to give the lowest Bit Error Rate (BER) is considered. Simulation results prove enhancement in performance when using the proposed adaptive strategy based UCA smart antenna. | ||||
