본 논문에서는 QPSK(Quadrature Phase Shift Keying) 확산에서 광대역 신호의 다중 협대역 간섭을 제거하는 데 유용한 복소 계수 적응형 IIR 노치 필터의 정상 상태 성능을 분석하는 방법을 제시합니다. 스펙트럼 통신 시스템. 단순화된 기울기 알고리즘을 기반으로 한 적응형 노치 필터가 고려됩니다. 노치 필터 출력의 조건부 평균과 분산에 대한 분석식이 개발되었습니다. 신호 대 잡음비 개선 인자도 구해지며, 이를 통해 노치 필터 사용의 타당성을 결론 내릴 수 있습니다. 마지막으로 이론적 예측을 확인하는 컴퓨터 시뮬레이션 결과가 표시됩니다.

Abstract: In this paper, we present a method to analyze the steady-state performance of a complex coefficient adaptive IIR notch filter which is useful for the rejection of multiple narrow-band interferences from broad-band signals in quadrature phase shift keying (QPSK) spread-spectrum communication systems. The adaptive notch filter based on the simplified gradient algorithm is considered. Analytical expressions have been developed for the conditional mean and variance of notch filter output. The signal-to-noise ratio improvement factor is also obtained from which the validity of the use of the notch filter can be concluded. Finally, the results of computer simulations are shown which confirm the theoretical predictions.
