In this paper, we analyzed the working phenomenon of Single and Multi carrier IDMA in Non Gaussian Impulsive medium and also compared their relative performances. The performance comparison is evaluated under the following constraints; by varying the iteration count, impulsive constant, control parameters and no. of users etc. The multi user detection for these schemes can be realized with complexity (per user) strictly independent of number of users. The simulation result concludes that multicarrier IDMA outperforms the single carrier IDMA in impulsive non Gaussian channel as a medium.

A new multi-code multicarrier code division multiple access (MC-MC-CDMA) system is proposed and analyzed in afrequency selective fading channel. By allowing each user to transmit an M-ary code sequence, the proposed MC-MC-CDMA system can support various data rates as required by next generation standards without increasing the interference which is common in general multicarrier CDMA systems. The bit error rate of the system is analytically derived in frequency selective fading, with Gaussian noise and multiple access interference. The results show that the proposed MC-MC-CDMA system clearly outperforms both single-code multicarrier CDMA (MC-CDMA) and single-carrier multi-code CDMA in a fixed bandwidth allocation.This indicates that MC-MC-CDMA can be considered for next generation cellular systems.
