摘　　要：CDMA技术的开发应用是为了增加系统的通信容量。而CDMA系统的系统容量与系统的信噪比密切相关。本文主要根据信息理论对DS－CDMA系统的容量作了简要分析，得到了系统总容量的边界．并说明了系统信噪比与容量的关系。The aim which the application and the development of CDMA technology is increas-ing the system capacity. However, the capacity of the CDMA system in close relationship with theSNR in the system. In this paper, the capacity of the DS-CDMA system is analysed that accordingto the infromation theory, and the relationship of the capacity and the SNR is showed.

关 键 词：信噪比 扩频通信 DS-CDMA 系统容量
