Abstract

In this paper performance of different basis in multicarrier modulation (MCM) system over time-variant channels are analyzed and filter bank generated by different orthogonal Daubechies wavelets and bi-orthogonal wavelets are tested and compared. Due to the high spectral containment of wavelet filters, the wavelet packet MCM (WP-MCM) system performs better than Fourier based MCM system over time-variant channels. With turbo code applied in WP-MCM system, the BER performance improves greatly over time-variant channels with few iterations in the regions of low signal to noise ratio
