MULTICARRIER CODE DIVISION MULITPLE ACCESS BASED ON WAVELET
Abstract
In this paper an alternative strategies will be demonstrated that mitigate interference without relying on the fact that the effective channel is shorter than the CP. Wavelet-based MC-CDMA has gained popularity in the literature recently. Due to very high spectral containment properties of wavelet filters, wavelet-based MC-CDMA can be better combat narrowband interference and is inherently more robust with respect to ICI than traditional FFT filters. The classic notion of a guard band does not apply for (DWT-MC-CDMA), hence data rates can enhanced those of FFT implementations.
