| 摘 要： | 针对跳频通信进行有效干扰的关键在于对跳频信号参数进行精确的估计,提出了一种基于重分配平滑伪魏格纳维尔分布(reassigned smoothed pseudo Wigner-Ville distribution,RSPWVD)的高速跳频信号跳周期估计算法。该算法利用了RSPWVD良好的时频聚集性和抑制交叉项的能力,能够有效地估计出跳频信号的跳周期参数(hop duration)。仿真实验结果表明了该算法的准确性与有效性。

| Abstract: | The key to jam frequency-hopping communication is to estimate its parameters efficiently and precisely.A algorithm for estimating the hop duration of frequency-hopping signals based on reassigned smoothed pseudo WVD(RSPWVD) is proposed.With the good ability of RSPWVD in time-frequency concentration and restraining cross-terms,this algorithm can efficiently estimate the hop duration of FH signals.Simulation results demonstrate that the estimation algorithm is effective and efficient. |
