Abstract:

A new multicarrier modulation system M band lifting wavelet multicarrier modulation (LWMT) system was proposed based on M band wavelet theory and its lifting scheme. Through analyzing bit error rate(BER) and simulated the system under additive white Gaussian noise(AWGN) channel and fading channel, the result shows that: in fading channel the performance of LWMT system is better than orthogonal frequency division multiplexing (OFDM) system. In AWGN channel the performance of LWMT system is same as OFDM system but LWMT system performance is superior to OFDM system in the antinarrow interference.

Key words: M band wavelet, wavelet lifting, orthogonal frequency division multiplexing, digital signal processing, lifting wavelet multicarrier modulation system
