다중 경로 페이딩 단일 코드(SC-) 및 다중 코드 CDMA(MC-CDMA) 시스템에서 멀티미디어 트래픽에 필요한 역방향 링크 신호 전력을 조사합니다. 다중 확산 코드 채널 간의 직교성 손실 효과는 직교성 인자를 도입하는 것이 특징입니다. 두 CDMA 시스템에 필요한 신호 전력은 확산 대역폭, 직교성 인자 및 확산 코드 수 등 다양한 시스템 매개변수를 사용하여 분석됩니다. 분석 결과에 따르면 단일 트래픽 유형만 전송하는 MC-CDMA 사용자는 단일 트래픽 유형만 전송하는 SC-CDMA 사용자보다 훨씬 더 많은 전력을 필요로 합니다. 반면, 멀티미디어 트래픽을 전송하는 MC-CDMA 사용자에게는 멀티미디어 트래픽을 전송하는 SC-CDMA 사용자와 거의 동일한 전력 수준이 필요합니다.

Abstract: The reverse link signal power required for multimedia traffic in multipath faded single-code (SC-) and multi-code CDMA (MC-CDMA) systems is investigated. The effect of orthogonality loss among multiple spreading code channels is characterized by introducing the orthogonality factor. The required signal power in both CDMA systems is analyzed with varying system parameters of spreading bandwidth, the orthogonality factor, and the number of spreading codes. Analytical results show that MC-CDMA users transmitting only a single traffic type require significantly more power than SC-CDMA users with only a single traffic type. On the other hand, MC-CDMA users transmitting multimedia traffic require power levels approximately identical to SC-CDMA users with multimedia traffic.
