摘　　要：直放站具有成本低、组网灵活、建设速度快等优点,成为蜂窝移动通信系统中提高覆盖、改善网络质量的重要手段。但直放站的引入也会给CDMA网络带来一些不利的影响。文中就CDMA直放站引入后对CDMA网络产生的噪声叠加、覆盖半径缩小、传输时延增加等影响进行分析,并提出相应的解决措施。Because of low cost, flexible networking and short time to service, the repeater using is a best and famous solution to extending the coverage and improving network quality in the cellular telecommunication system. CDMA repeater will bring with it some bad effects on CDMA network. In this paper, some bad effects such as noise adding, coverage degrading and additional delay are analyzed firstly, and then some solution are presented.
