摘要
载波频率测量是通信侦察和通信对抗的重要内容。针对多径信道,利用数字信号处理技术,提出了在频域进行载波频率测量的一种实用算法,并进行了计算机仿真。仿真结果表明,该算法是可靠的、有效的和健壮的,SNR≥-10dB时相对误差不大于0.48%。
Aimed at multi - path channels, an applied algorithm of carrier frequency＇ s detecting has been put up in the frequency domain making use of digital signal processing technology, and computer simulation has been engaged in. It is showed that this algorithm is reliable, effective and robust, and the relative error is less than 0.48% when SNR is not less than - 10dB.
