摘要 在基于平方率的能量检测脉冲超宽带通信系统中,采用了较简单的模拟脉冲锁相环实现脉冲信号的同步和到达时间(TOA)的估计。提出了利用模拟延迟锁相环(ADLL)构建一种精确度高、实现简单的TOA估计算法;并对该算法性能进行了分析。仿真验证了该方法的有效性,并解决了在非视距(NLOS)环境下的精确测距问题。 An IR-UWB(impulse-radio ultra-wideband) communication system of energy detection based on square uses simple analog pulses PLL(Phase Locking Loop) to synchronization and time of arrival(TOA) estimation.In this paper,it presents using the analog delay locked loop(ADLL) to construct the simple and the high precision TOA estimation algorithm;it also analyzed the performance of the algorithm.Simulation results show the effectiveness of the method,also resolves the exact distance estimation in non line of sight(NLOS) environment.
