Improve the Performance of Multi-users MC-CDMA Based on Critically Sampling Multi-wavelet Transform over Wireless Propagation Channel
In this paper, Critically Sampling Inverse Discrete Multi-Wavelet Transform (CSID-MWT) are proposed as a modulator technique instead of Inverse Fast Fourier Transform (IFFT) in the realization of the Multi-Carrier Code Division Multiple Access (MC-CDMA) system. The proposed structure improved the bandwidth efficiency through the elimination of the cyclic prefix (CP) due to the good orthogonality and time-frequency localization properties of the Multi-Wavelet transform. The proposed system was simulated using MATLAB to allow various parameters of the system to be varied and tested. Simulation results showed that the proposed system outperforms conventional MC-CDMA system, and its performance is superior to that of the conventional MC-CDMA with CP.
