본 논문에서는 인접한 여러 CDMA/DSSS의 채널 대역이 주파수 영역에서 중첩되는 경우 CDMA(코드 분할 다중 접속) 시스템에 대한 성능 평가를 수행합니다. 모든 시스템은 직접 시퀀스 확산 스펙트럼(DSSS) 기술을 채택하고 서로 다른 반송파 주파수에 의해 BPSK 변조된다고 가정합니다. APC(자동 전력 제어)도 간섭을 받는 시스템에 적용되어 수신기가 모든 사용자로부터 동일한 전력을 얻습니다. 손실 일반성이 없으면 분석 중에 AWGN(Additive White Gaussian Noise) 채널도 가정됩니다. 본 논문에서는 두 CDMA 시스템이 서로 다른 반송파 주파수에 의해 변조되는 신호 대 잡음비(SNR)의 분석 솔루션이 먼저 도출되었습니다. 이 분석은 일반적인 경우에 적합합니다. 그 결과 뛰어난 계산 성능을 보여줍니다. 특히 시스템이 반송파 차이 없이 동일한 코드 길이를 가질 때 결과는 Pursly의 결과와 매우 유사합니다.

Abstract: This paper conducts performance evaluation for a code division multiple access (CDMA) system when channel bands of multiple neighboring CDMA/DSSS are overlapped in frequency domain. It is assumed that all systems adopt direct-sequence spread-spectrum (DSSS) technique and are BPSK modulated by the different carrier frequencies. Automatic power control (APC) is also applied in the interfered system such that the receiver gets the same power from all users. Without loss generality, an additive white Gaussian noise (AWGN) channel is also assumed during analysis. In this paper, the analytic solution of the signal to noise ratio (SNR) is first derived in which both CDMA systems are modulated by different carrier frequencies. This analysis is good for general cases; and the result shows an excellent computational performance. In particular, the result is very close to Pursly's result, when the systems have the same code length with no carrier difference.
