代码说明:

   扩频通信,从电磁波利用来看,与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据(窄带信号)的频谱进行扩展,形成宽带的低功率谱密度信号发射,使用不同的伪随机序列编码,不同通信用户可在同一频段、同一时间工作,互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)
