基于双耦合Duffing振子的随机相位正弦信号检测 采用双耦合混沌振子阵列实现了随机相位微弱正弦信号的检测，在此基础上，提出了新的检测方法，即利用单个耦合混沌振子，通过临界及周期状态 的变化检测随机相位微弱正弦信号并大致估计信号相位范围，该方法比双耦合混沌振子阵列法简单，更易于实现。-Based on double coupled Duffing oscillators random phase sine signals detected by two coupled chaotic o

这是有关正弦波频率估计的几种算法，包括过零点检测，rife算法，music算法，levensen法，周期图法等7种不同算法。-This is several algorithm for frequency estimation of sinusoid, including zero crossing detection, rife algorithm, music algorithm, levensen method, periodogram method 7 different algorit

This is a matlab code to do monte carlo on detection of a sinusoid in AWGN. The PD vs ENR could be calculated and plotted.
