Wavelet-packet-transform for narrow-brand-interference suppression in direct sequence spread spectrum communication system
YU Shao-peng · Journal of Harbin University of Commerce · 2008
Multi-band wave packet transform has the merits in excellent smoothness,linear phase and compact support.With the traditional wave packet decomposition tree and filter,the data are decomposed by the wave packet to suppress the narrow band interference.The results show that the wave packet transform algorithm for narrow band interference suppression has the outstanding performance and superexcellent bit error rate(BER).
