研究了重频参差相参脉冲串的频率估计算法。通过脉内相关积累,提高了新序列的信噪比。对新序列的相位差按参差重数抽样平均,减小了等效的相位噪声方差,利用重频参差比解相位模糊,扩大了频偏允许范围,降低了算法的信噪比门限。分析了本算法实现相参频率估计的条件,推导了相应信噪比门限的解析表达式,指出了信噪比门限与信号样本总数、参差重数、参差比之阎的关系。仿真结果表明:上述结论是正确的,在满足信噪比门限条件下,频率估计的精度接近相参脉冲串频率估计的克拉美一罗限(CRLB)。(Frequency Estimation for Staggered Coherent Pulse Train)

noTHtransmitPAM
此函数用于产生脉冲超宽带系统的训练序列的波形。输出参数有三个:bits--发送的数据,stx--发送的信号,ref--参考信号
发送端调制方式为TH-PAM(The emerging ultra-wideband (UWB) system offers a great potential
for high data rate wireless multimedia applications of the home
entertainment and industry, as well as for low data rate sensor
networks involving low power devices~cite{paragraph1}. One of the
most acute challenges in realizing these potentials of the UWB
systems is the timing acquisition. Timing errors as small as
fractions of a nanosecond could seriously degrade the system
performance~cite{paragraph21}. The difficulty in UWB
synchronization arises from UWB signals being the ultrashort
low-duty-cycle pulses operating at very low power density.)
