摘　　要：文章通过扩频通信技术有关性能分析和仿真,得出了扩频通信对多径干扰具有很强的抑制能力,可以有效地解决限定空间内移动通信质量急剧下降问题。The multipath decline is severe in limited space （such as in tunnel, in laneway and in building）, so the quality of mobile communication in it drops sharply. The ability of spread spectrum communication technique to resist multipath decline is studied, the expression of SNR and BER of the system using spread spectrum communication technique is educed, a bit error curve of simulation with a rectangle tunnel model is got and the simulating result demonstrates that the performance of the system to resist multipath decline is improved awfully.
