摘要
本文对多路测量信号的扩频传输系统进行了研究,提出了对所传信号的频谱进行扩展并利用码分复用实现多路信号的复用传输的方法。分析了多路检测信号的扩频传输系统性能,其误码特性比非扩频系统有很大提高,且系统大为简化。
In this paper spread spectrum transmission system of multiplex detecting signal is studied. The method of transmission after multiplex detecting based on signal spread spectrum and code division multiplexing is mentioned. The capability of spread spectrum transmission system of multiplex detecting signal is discussed. The capability of spread spectrum transmission system is better than non- spread spectrum system, and system is simplified.
