摘要
从理论上分析比较了FDMA,TDMA与CDMA蜂窝网系统的频谱效率,指出了其频谱效率的限制因素和提高方法,计算了Q-CDMA,GSM与TACS三种实用蜂窝网系统的频谱效率,得出了几点有用结论。
This paper theoretically analyzes and compares the spectral efficiency of the FDMA,TDMA and CDMA cellular systems,points out the restrictive factors of their spectral efficiency and some ways of improving it,calculates the spectral efficiency of three practical cellular systems,i.e.Q CDMA,GSM & TACS,and draws several useful conclusions.
