| 摘 要： | 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。

| Abstract: | In Ultra-Wideband Communication System ,Gaussian monocycle is selected. In this paper,a novel chirp signal for UWB systems instead of the conventional Gaussian monocycle is proposed. Based on the excellent autocorrelation between UP-Chirp and DOWN-Chirp and its realization by surface acoustic wave devices,the proposed system is easy to implement,low in power consumption,and of low cost and low complexity. Frequency Hopping Communication is covered,not easily captured,and excellent in resisting interference. |
