본 논문에서는 CDMA 통신 시스템에서 협대역 간섭 제거를 위한 KLT(Karhaunen-Loeve Transform) 기반의 여러 단위 변환 영역 필터링 기술을 제시합니다. KLT를 선택한 이유는 협대역 간섭의 에너지를 패킹한다는 점에서 최적의 단위변환이기 때문이다. 결과적으로 이 변환을 적용한 후 변환된 신호의 작은 부분이 협대역 간섭의 간섭을 받게 되므로 XNUMX으로 설정해야 합니다. 최적 변환(KLT)을 사용할 수 없기 때문에 여러 차선의 변환을 제시하고 그 성능을 이산 푸리에 변환(DFT) 및 이산 코사인 변환(DCT)과 같은 잘 알려진 기존 변환 방법과 비교합니다. AR(자동 회귀) 및 정현파 협대역 간섭 모두. 시뮬레이션 결과는 제안된 변환 방법이 기존 방법보다 훨씬 뛰어난 성능을 보인다는 것을 보여줍니다.

Abstract: In this paper, we present several unitary transform-domain filtering techniques based on Karhaunen-Loeve Transform (KLT) for narrow-band interference rejection in CDMA communication systems. The reason for selecting the KLT is that it is an optimum unitary transform in the sense of packing the energy of the narrow-band interference. As a result after applying this transform, a small portion of the transformed signal would be interfered by the narrow-band interference, and thus must be set to zero. Due to unavailability of the optimum transform (KLT), several sub-optimum transforms are presented and their performances are compared with the well-known conventional transform methods such as Discrete Fourier Transform (DFT) and Discrete Cosine Transform (DCT) in the presence of both Auto Regressive (AR) and sinusoidal narrow-band interference. Our simulation results show that the proposed transform methods significantly outperform the conventional methods.
