扩展频谱为通信系统提供了良好的抗干扰性能和多址寻址能力,被广泛应用于军事和民用通信系统中。跳时扩频通信中的信号频谱不仅能容忍较大的外界干扰,而且由于脉冲波所含能量极少,几乎不会使信号相互干扰,信号的隐蔽性极好;同时跳时通信具有超宽带特性,因而应用前景十分广阔。 Spread spectrum provides good anti-jamming performance and multiple addressability for communication systems and is widely used in military and civil communication systems. The signal spectrum in time-hopping spread-spectrum communication can not only tolerate large external interference, but also can hardly interfere with each other due to the very little energy contained in the pulse-wave, and the concealment of the signal is excellent. Meanwhile, Features, so the application prospects are very broad.
