跳时扩频通信及其抗干扰性能分析

Time Hopping communication and the analysis of anti-interference function

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。

Time Hopping communication can not only endure the bigger interference from outside,but also make signal immune to internal interferences because the pulse wave contains minimum amount of energy.The concealment and the anti- interference function of the signal are good.Time Hopping can be extensively applied in the military and public correspondence system inside because of its super brand.
