摘　　要：现代复杂的通信环境下，多种通信系统同时使用，就存在窄带数字系统与宽带CDMA系统的战场兼容共存问题。常用的方法是将窄带数字信号近似为多个正弦波叠加或AR模型信号计算对宽带CDMA系统的影响，通过分析可知这种数学推导是有缺陷的，因此介绍了改进的方法并给出结果。In the complex circumstance of communication, the problem of compatibility between narrowband digital system and broadband CDMA system is remarkable. The usual method that takes narrowband digital signal as the summation of several sine waves or as AR models is deficient. And it is proved through analysis, a method that can improve this deficiency is presented.
