摘　　要：文章介绍了与全球移动通信系统(GSM)接收灵敏度和有线接入移频直放站相关的基本概念,完整地计算出了极限工程应用环境下基站和直放站的接收灵敏度,并分析了不同的直放站上行链路增益分配对整个系统灵敏度的影响,最后给出直放站工程应用中合理分配链路增益以优化系统灵敏度的方法。This paper first introduces the basic concept that is relavant to the receiving sensitivity of GSM systems and cable access frequency shifting repeaters. Then, it calculates the receiving sensitivity of Base Transceiver Stations （BTS） and repeaters under extreme conditions, and analyzes the influences of different repeater uplink gain distributions on the sensitivity of the entire system. Finally, it presents the rational distribution of the link gains of repeaters in project applications for the optimization of the system sensibility.
