摘　　要：为了解决用户数量迅速增加而引起高话务地区的基站话务密度增长问题,涉及共享一个统计复用的系统扩容问题,针对通信系统的扩容问题,在原有载波下增加基站容量配置、增加新载波、增加新基站等可选择方案中,必须采用适当的增加载波的方法,多载波调制技术是解决高的话务密度所需高容量的重要方法。围绕着对CDMA技术的相关内容进行了系统的介绍,阐述了MCM系统的信号模型,并对MCM系统性能进行了较全面的分析。计算机模拟的结果表明了仿真与理论的一致性。To solve user quantity quick increase and arouse the base station words affir density of high words affir area to present increase problem is concerned with to share a system that statistics uses again expand to allow problem, according to communication, is systematic to expand to allow problem , increase base appearance of terminal under original signal carrier to measure disposition , increase new signal carrier , increase new base station can select to, in scheme, must adopt the proper method that increases signal carrier, carrier modulation technology is that the words affir density of high solution needs the important method of high capacity. Article revolves around the related content for the technology of CDMA and has gone on , is systematic to introduce , have elaborated the signal model of MCM system , and have carried out more overall analysis for MCM systematic performance. The analog result of computer has shown the consistency of emulation and theory.
