求一个复正弦加白噪声随机过程的信号：

xn=exp(j*pi*n-j*pi)+exp(j*w0*n-j*0.7*pi)+v v(n)为零均值白噪声。S/N=10dB。取P=3，构造4阶的自相关矩阵R的基于MUSIC算法的功率谱估计的MATLAB程序-For a complex sinusoid plus white noise of the signal random process: xn = exp (j* pi* nj* pi)+ exp (j* w0* nj* 0.7* pi)+ v　v (n) zero mean white noise. S/N = 10dB. Take P = 3, constructed of 4-order auto-correlation matrix R of the MUSIC algorithm based on power spectrum estimation procedure of MATLAB
