미래 무선 서비스를 향한 CDMA 네트워크 진화의 수단으로 N-CDMA(협대역 CDMA) 및 W-CDMA(광대역 CDMA) 시스템의 스펙트럼 오버레이가 [8]에서 제안되었습니다. 오버레이 전략을 정당화하기 위해 동일한 작업에서 역방향 링크 용량을 검토합니다. 기존 CDMA 셀룰러 시스템의 용량은 일반적으로 역방향 링크에 의해 제한되지만 특정 CDMA 제안에 채택된 전송 기술에 따라 순방향 링크에서 제한이 발생할 수 있습니다. 특히, 두 링크 간에 불평등한 트래픽이 제공되는 미래 모바일 서비스 환경에서는 시스템에서 동시에 수용할 수 있는 사용자 수는 순방향 링크에 의해 제한될 수 있습니다. 본 논문에서는 먼저 스펙트럼적으로 중첩된 협대역 및 광대역 CDMA(N/W CDMA) 시스템의 순방향 링크 용량을 조사합니다. 그리고 이를 역방향 링크 용량과 비교하여 전체적인 성능을 구합니다. N/W CDMA 시스템의 용량에 대한 다양한 매개변수의 영향은 다양한 모바일 환경에 대해 수치적으로 평가됩니다.

Abstract: As a means of CDMA network evolution toward future wireless services, a spectral overlay of narrowband CDMA (N-CDMA) and wideband CDMA (W-CDMA) systems is proposed in [8]. In order to justify the overlaying strategy, the reverse link capacity is examined in the same work. Although the capacity of conventional CDMA cellular systems is usually limited by the reverse link, the limit could occur at the forward link depending on the transmission technologies adopted by specific CDMA proposals. Especially, the number of users that can be simultaneously accommodated in the system would be limited by the forward link in future mobile service environments where unequal traffic is offered between two links. In this paper, we first examine the forward link capacity of the spectrally overlaid narrowband and wideband CDMA (N/W CDMA) system. And we compare it with the reverse link capacity to obtain the overall performance. The effects of various parameters on the capacity of N/W CDMA system are numerically evaluated for different mobile environments.
