GSM/GPRS通信终端发射功率控制及校准方法

Control and calibration of the transmission power of mobile communication terminal in GSM/GPRS

研究了GSM/GPRS系统中移动通信终端发射功率控制的必要性和原理及其移动通信终端功率控制的实现流程,在此基础上提出了曲线模拟和折线模拟两种方法,以实现移动通信终端发射功率校准,以及发射功率的精确控制,并对这两种方法进行了实际验证.验证结果表明采用基于这两种方法的校准都能较好地满足GSM/GPRS协议对移动通信终端发射功率的规定.并基于验证结果对它们各自的优缺点进行了分析、比较.还对前面提出的方法进行了推广,考虑了其在一般无线通信系统射频发射功率精确控制中的应用.

The necessity and principles of the power control of mobile terminals in global system for mobile communication/general packet radio service(GSM/GPRS) system were explained.Realization of the transmission powers control was described generally.Two methods to calibrate the transmitting power of the mobile terminal were presented.The two methods were verified in practical environment,and the result matched the GSM/GPRS protocol′s requirement on transmitting power of the mobile terminal very well.Then an analy...
