摘要
通过将接收信号功率描述为对数正态分布的随机变量，其标准方差表示功率控制的误差，分析了在ＣＤＭＡ蜂窝系统中，功率控制误差、软切换方案及话音激活技术对ＣＤＭＡ蜂窝系统性能的影响．计算表明，采用精确的功率控制技术。
The received signal power was modeled as a log normal random variable, the power control error was described by the standard variance. The performance of the CDMA cellular system with imperfect power control was analyzed.The influences of different soft hand off schemes and voice activity were also investigated.The results indicate that adopting perfect power control technology, resonable soft hand off scheme and voice activity technology are beneficial to the CDMA cellular system.
