基于WCDMA中的容量及覆盖的分析

以CDMA无线小区规划为基础，探讨解决地理位置上各个基站的空间无线信道在各小区上最大分配与由此产生的系统内及系统间的干扰之间的矛盾，以及一定的无线覆盖区内的信道数和最大限度的安装用户数之间的矛盾等核心问题。结合工程规划的理论和方法，分别对限制前向和反向信道的容量加以分析，初步解决了包括路径损耗预测、前反向覆盖预测前反向平衡等模块的算法建模。仿真分析结果表明，该算法能较大程度上克服移动用户接收端的干扰影响，满足用户所需的信干比要求。

Study on capacity and cover of the WCDMA

This paper mainly discusses the solution to the contradiction between intra-system and the systems in the maximum allocation of Base Station Space wireless Letter Pass in cells and the nuclear problems such as the contradiction between the number of wireless channel covering space and the maximum number of installation. Acconding to the theory and means of project layout, the paper analyses the capacity of the preceding reversion covers, resolves the arithmetical modeling of the modules,such as path loss forecasting, capacity accounting and preceding reversion balance etc. The result of simulation analysis shows that the method can be used to overcome the disturbance, then mobile users receive the message to a higher degree to satisfy users with ratio message disturbance.
