Abstract :
Intense interest has focused on modulation techniques which can provide broadband transmission over wireless channels for applications including wireless multimedia, wireless local loop, and future generation mobile communication systems. Multicarrier modulation techniques, including OFDM and OWPDM are among the promising techniques. Because of some drawbacks of the OFDM and OWPDM system, we introduce bi-orthogonal wavelets as subcarrier basis functions. The performance of the system is simulated and analyzed on the AWGN and flat Rayleigh channel. The introduction of the bi-orthogonal wavelet is the most important step in practical implementation
