본 논문에서는 DS-CDMA 시스템에서 단일 사용자 검출을 위한 새로운 간섭 제거 기법의 성능을 조사하였다. 이 새로운 알고리즘은 PN(Pseudorandom Noise) 시퀀스의 Cycle-and-Add 속성을 기반으로 하며 동기식 및 비동기식 시스템 모두에 적용할 수 있습니다. 제안하는 전략은 간섭의 전력 레벨에도 불구하고 간섭 신호를 하나씩 삭제할 수 있는 간단한 방법을 제공한다. 따라서 TPC(Transmit Power Control) 기술을 사용하지 않고도 NFP(Near-Far Problem)를 연속적으로 극복하는 것이 가능하다. 제안된 절차의 타당성은 AWGN(Additive White Gaussian Noise) 및 주파수 비선택적 페이딩 채널의 컴퓨터 시뮬레이션을 통해 확증됩니다. 성능 결과는 제안된 수신기가 기존 수신기보다 성능이 뛰어나며 많은 경우 상당한 이득을 얻음을 나타냅니다.

Abstract: In this paper, performance of a novel interference cancellation technique for the single user detection in a direct-sequence code-division multiple access (DS-CDMA) system has been investigated. This new algorithm is based on the Cycle-and-Add property of PN (Pseudorandom Noise) sequences and can be applied for both synchronous and asynchronous systems. The proposed strategy provides a simple method that can delete interference signals one by one in spite of the power levels of interferences. Therefore, it is possible to overcome the near-far problem (NFP) in a successive manner without using transmit power control (TPC) techniques. The validity of the proposed procedure is corroborated by computer simulations in additive white Gaussian noise (AWGN) and frequency-nonselective fading channels. Performance results indicate that the proposed receiver outperforms the conventional receiver and, in many cases, it does so with a considerable gain.
