| Abstract: | 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. |
