Abstract :
Wavelet-based MC-CDMA has recently gained popularity in literatures and due to very high spectral containment properties of wavelet filters, Wavelet-based MC-CDMA can better combat narrowband interferences and is inherently more robust to ICI than traditional FFT filters. Moreover, since the classic notion of a guard band does not apply for DWT-MC-CDMA; an alternative strategy that mitigates interference without relying on the fact that the effective channel is shorter than the CP is presented in this paper, hence data rates can be enhanced over those of FFT implementations.
