A study on narrowband interference rejection in PN spread spectrum communication system

PN 대역 확장 통신시스템에서 협대역 간섭신호의 제거방식에 관한 연구

In this paper, a improved whitening filter for narrowband interference rejetion in PN spread spectrum communication systems is proposed. This whitening filter has the feedback from the output to the input of adaptive transversal filter and is superior to conventional LMS whitening filter in respect to SNR and power spectrum since the calculation of tap weight is based on maximum likelihood estimation
