Abstract :
We propose a novel scheme of M-ary multicarrier spread spectrum based on wavelet packet. The scheme has good performance in multipath channel because of taking advantages of the properties of wavelet packet. Its performance is investigated for a multipath, slow Rayleigh fading channel. The performance advantages of the system over that based on DFT are demonstrated by both analytical and simulation methods.
