摘要：
Two new Narrow Band Interference (NBI) suppression methods based on Multi-band Wavelet Packet Transform (MWPT) and Complex Wavelet Packet Transform (CWPT) in Direct Sequence Spread Spectrum (DSSS) systems are presented in this paper. With these two techniques, jammed DSSS signal is decomposed separately using MWPT and CWPT in order to separate desirable signal from jamming signal. The DSSS signal is recovered by wavelet reconstruction after the interference signal is filtered out. The results of our simulations show that these two techniques outperform the scheme based on 2-band wavelet packet transform.
