Performance Analysis of Adaptive Modulation for Distributed Switch-and-Stay Combining with Single Relay
Abstract
In this paper we present our investigation of the performance of a distributed switch-and-stay scheme and a solution for low-complexity cooperative relaying under adaptive transmission. We are able to derive the closed-form expressions of the occurrence probability, the outage probability, the bit error probability, and the achievable spectral efficiency of the proposed scheme for Rayleigh fading channels. Simulations are performed to verify the analytic results. It is shown that, by applying adaptive modulation, the achievable spectral efficiency of the system is improved significantly, and the proposed scheme achieves the same spectral efficiency as compared to that of the incremental relaying but with a lower relay activation time.
