Capacity Analysis of VSG-CDMA System

摘要: 该文研究分析了非理想功率控制下,多种类型用户并存时VSGCDMA系统的容量问题。文中根据小区内干扰Iin和他区干扰Iother导出了用户接入许可条件,该条件对用户均匀分布和非均匀分布情况均适用。在此基础上文中推导了链路失败概率的计算公式,并导出了他区用户的干扰分布。Abstract: In this paper, the capacity of VSG-CDMA system with power control imperfections in the presence of multiplicate types of users is discussed. Admission criterion is derived according to the interference of inter cell Iin and other cell Iother, the admission criterion can be used for uniformity distribution or non-uniformity distribution of users. Formulas to calculate link failure probability and the distribution of other cells interference are also deduced.
