Performance Comparison of IDMA and CDMA Systems Based on Simulink

This paper presents the performance comparison of interleave division multiple access (IDMA) and code division multiple access (CDMA) systems based on Simulink. We investigate the basic principle that illustrates the similarities and differences of the two different schemes. According to these schemes, we analyze every model function and build simulation platforms for these systems. The simulation platforms can realize the performance simulation flexibly by setting the main parameters of the models conveniently. We take the chirp interference as example to test the anti-jamming performance of IDMA and CDMA. Simulation and test results show that IDMA performs better than CDMA despite its simplicity.
