The analysis showns that MRC decreases the outage probability and increases the system coverage, compared with the soft handoff in a CDMA system. 研究结果表明它比码分多址中的软切换中所采用的选择式宏分集能够带来更低的中断率，从而提高系统的覆盖。
The author has described several key techniques for improving the capacity of CDMA digital celullar system,comparing to the spectral efficiency of FDMA and TDMA cellular system. 本文对照频分多址和时分多址系统的频谱效率，阐述了码分多址系统提高系统容量的几项关键技术。
