Como meio de evolução da rede CDMA em direção a futuros serviços sem fio, uma sobreposição espectral de sistemas CDMA de banda estreita (N-CDMA) e CDMA de banda larga (W-CDMA) é proposta em [8]. Para justificar a estratégia de sobreposição, a capacidade do link reverso é examinada no mesmo trabalho. Embora a capacidade dos sistemas celulares CDMA convencionais seja geralmente limitada pelo link reverso, o limite pode ocorrer no link direto dependendo das tecnologias de transmissão adotadas pelas propostas específicas de CDMA. Especialmente, o número de utilizadores que podem ser simultaneamente acomodados no sistema seria limitado pela ligação directa em futuros ambientes de serviços móveis onde é oferecido tráfego desigual entre duas ligações. Neste artigo, primeiro examinamos a capacidade do link direto do sistema CDMA de banda estreita e banda larga sobreposto espectralmente (N/W CDMA). E comparamos com a capacidade do link reverso para obter o desempenho geral. Os efeitos de vários parâmetros na capacidade do sistema N/W CDMA são avaliados numericamente para diferentes ambientes móveis.

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.
