Rejection of Narrowband Interference Based on Wavelet Packet Analysis
Han Zhaohui · Information and Electronic Engineering · 2006
Wavelet packet transform can provide multi-scale time-frequency detail for both signal and interference.In order to reject narrowband interference,wavelet packet analysis together with reconstruction are used for denoising study to improve signal performance.It is proved to be effective through a simulation example of denoising in the presence of both discontinuous and continuous narrow band interference.
