The effect of impulsive noise on the performance of multi carrier code division multiple access (MC-CDMA) systems and analyze the performance by examining the MC-CDMA system model in time domain. The authors have discovered that conventional Walsh-code based MC-CDMA is less robust to the presence of impulsive noise than the corresponding Direct Sequence (DS) CDMA and Multi Carrier Modulation based (MCM) systems. Furthermore, it is demonstrated that the performance of MC-CDMA depends strongly on the selection of the utilized spreading codes.
