Analysis of Optimal Spectral Efficiency with Adaptive Modulation Coding and Cooperative ARQ Protocols

摘要：

　　In this paper aiming at maximizing the spectral efficiency,a cross-layer design which combines adaptive modulation and coding (AMC) at the physical layer and truncated automatic repeat request (ARQ) protocol at the data link layer in cooperation system is proposed.In order to analyze the system performance,we first derive a closed form expression of probability density function (PDF) of the received signal-to-noise (SNR) using maximum ratio combing (MRC) at the destination node,the theoretical results and simulation show that the new design outperforms the traditional AMC system especially at low SNR.
