Performance Analysis of MIMO MC-DS/CDMA System Using Chaotic Spreading Sequence

V. Nagarajan and P. Dananjayan

Abstract—This paper presents a novel chaotic spreading sequence for multiple input multiple output multi-carrier direct sequence code division multiple access (MIMO MCDS/ CDMA) systems. The effect of multiple access interference can be mitigated by choosing the spreading sequences with appropriate cross-correlation properties. The performance of the system is analysed in multiuser scenario with the aid of simulation. The simulation results show that the proposed chaotic code spreading approach achieves a significant improvement in system utility and combats multiple access interference (MAI). The analysis reveals that the proposed system achieves significant performance improvement compared to Walsh Hadamard spreading code in MIMO MCDS/ CDMA systems.
