摘　　要：研究了低信噪比条件下,(互)相关解调和多重自相关两种不同的微弱正弦信号检测方法,利用MATLAB/SIMULINK分别对这两种算法进行仿真并对结果进行分析,最后作出比较总结。Two different methods, cross - correlation demodulation and multi - layer autocorrelation, for detecting weak sine signal in the condition of low SNR are studied. Simulations are made by using MATLAB/SIMULINK and the result is analyzed. In the end of this paper a comparison is made as well as the summary.

关 键 词：弱信号检测 相关解调 多重自相关
