In this paper, the authors consider the Bit Error Rate (BER) performance analysis of a cooperative relay communication system for Multi-Layer IDMA (ML-IDMA) using Maximal-Ratio-Combining (MRC) technique. They examine the effect of layers number on the performance and derive the average bit error probability of the Amplify-and-Forward (AF) relay scheme by using the closed-form relay link Signal-to-Noise Ratio (SNR). The proposed system has been simulated to evaluate the performance of ML-IDMA with different numbers of layers and different number of relays in the ML-IDMA cooperative environment.
