跳频信号的跳周期估计
Hop duration estimation for frequency-hopping signals
摘要
Abstract
Aiming at the actual application of communication countermeasure, a new method about accurately estimating the hop duration was proposed for the Frequency-Hopping(FH) signals. It applied Short Time Fourier Transform(STFT) to process FH at first, then obtained the peak sequenee from the results of STFT, and sampled the peak sequence in single-bit way, so the hop duration estimation could he obtained from the final single-bit sample sequence. The algorithm was simulated and its results and performance were analyzed. It is showed that the algorithm is efficient when SNR is greater than -1 dB. The method is simple, effective and easy to be implemented.关键词
