摘要

经典的CDMA蜂窝系统下行功率控制分析忽略了移动接收机中的背景噪声，通过求解特征值问题来解决等信干扰比问题。在考虑背景噪声的情况下，我们得到了一个包含前面结果的通解，并且在最小传输功率的意义上是最优的。给出了齐次系统的详细说明，并给出了非齐次系统的一般公式。

General analysis of downlink power control in CDMA systems

The classical analysis of the downlink power control in CDMA cellular systems neglects the background noise in the mobile receivers and leads to a solution for the equalized signal-to-interference ratio by solving an eigenvalue problem. By considering the background noise, we obtain a general solution that includes the previous result and is optimal in the sense that it minimizes the transmitted power. Detailed illustration is presented for an homogeneous system and a general formulation is given for non-homogeneous systems.
