| 摘 要： | 近年来通信信息的数字解调技术引起了人们的广泛关注，本文根据MSK信号的数学特征，提出了一种基于MSK信号特殊点FFT的实部或虚部比较判决的方法来实现MSK信号的数字解调。推导了在高斯白噪声背景下该方法的误码情况。计算机仿真结果表明该算法是简单、有效的。与传统的MSK最佳解调方法相比本算法对载波频偏不敏感，可以应用于一些通信侦察和截获的场合。 |

| Abstract: | The digital demodulation method of communication signal is widely concerned recently According to the mathematic characteristic of MSK signal, a digital demodulation method for the MSK signal based on the FFT is presented in this paper The theory result of the performance on the Gauss white noise channel is given The computer simulation proved the method to be simple and efficient The performance of the new method is less sensitive than it of the classic method, so it can be used in the ECM system |
