摘要
改进了利用模拟锁相环捕获UWB信号的电路模型,研究了提取信号时钟的方法,并在此基础上提出了通过二分搜索得到脉冲位置和信号帧定时的算法.采用的方法电路实现简便,仿真结果和分析表明,具有定时精确和捕获时间短的优点.
The UWB signal acquisition circuit based on the analog PLL is improved. A method to obtain the signal clock is studied, and then on the base of this circuit a binary search algorithm is proposed to obtain the pulse position and the timing of the signal frame. The circuit of this method can be realized easily. The simulation results and analysis indicate that it has the merits of precise timing and fast acquisition. It is of considerable reference value for the realization of UWB communication.
