摘　　要：蜂窝网采用空间频率再用技术大大地缓解了频谱资源有限与用户不断增长之间的矛盾。其中CDMA蜂窝网的容量最大,而且还具有软容量特性。但是由于CDMA是自干扰系统,它在直接应用ErlB定理之前受空间Erl容量概念的制约。本篇文章简要分析了在CDMA系统中计算Erl容量的方法,并涉及了一些针对这一CDMA特有概念的优化工作。The space frequence multiplex technology in cellular network greatly relieves thecontradiction between the limited spectrum resource and rapid increase of subscribers. The capability ofCDMA cellular system is the largest, besides has the characteristic of soft-capability. Because of self-disturbed system, it is limited by the space Erlang capability when applying the Erlang B theorem. The article analyzed the method of calculating Erlang capability in CDMA system, finally some optimization work was involved about the characteritis of CDMA.
