目前在超宽带通信系统中,普遍采用的脉冲波形是高斯脉冲波形。用Chirp信号来代替高斯脉冲信号,由于正向和反向线性调频脉冲具有良好的自相关性以及Chirp信号可以用声表面波器件实现,具有系统易于实现,功耗低,复杂度低等特点,同时,跳频通信比较隐蔽难以被截获,具有良好的抗干扰能力。 Currently in ultra-wideband communication system, the commonly used pulse waveform is Gaussian pulse waveform. Chirp signal instead of Gaussian pulse signal, the forward and reverse chirp pulse with good autocorrelation and Chirp signal can be achieved with surface acoustic wave devices, with the system easy to achieve, low power consumption, low complexity, etc., At the same time, frequency hopping communication is more difficult to be intercepted, with good anti-interference ability.
