代码说明:

  信号为两个正弦信号加高斯白噪声,各正弦信号的信噪比均为10dB,长度为N,信号频率分别为 和 ,初始相位 ,取 , 取不同数值:0.3,0.25。 为采样频率。分别用Levinson递推法和Burg法进行功率谱估计,并分析改变数据长度、模型阶数对谱估计结果的影响。(Signal into two sinusoidal signals applied Gaussian white noise, the SNR of each sinusoidal signals are 10dB, a length of N, respectively, and the signal frequency, initial phase, take, take different values: 0.3,0.25. It is the sampling frequency. Respectively Levinson recursion method and Burg method for power spectrum estimation, and change the length of the data analysis, the impact of model order estimation result spectrum.)
