In this paper, we consider the bit error rate performance analysis of a cooperative relay communication system on Multi-Layer Interleave Division Multiple Access (ML-IDMA) using Maximal-Ratio-Combining technique; we examine the effect of layers number on the performance and derive the average bit error probability of the Amplify-and-Forward (AF) and Decode-and-Forward (DF) relay schemes by using the closed-form relay link Signal-to-Noise Ratio and compare between these relaying protocols. Based on the analysis, and simulation results, it is shown that although degradation in the performance is observed in both relay schemes when increasing number of layers but on the other hand we saved in the band width. Slightly performance enhancing is obtained when using DF compared to AF relaying protocol.
