代码说明：

说明：小波阈值去噪的基本思想是先设置一个临界阈值λ，若小波系数小于λ，认为该系数主要由噪声引起，去除这部分系数;若小波系数大于λ，则认为此系数主要是由信号引起，保留这部分系数，然后对处理后的小波系数进行小波逆变换得到去噪后的信号。(The basic idea of wavelet threshold denoising is to set a threshold value of lambda first. If the wavelet coefficient is less than lambda, it is considered that the coefficient is mainly caused by noise and this part of the coefficient is removed. If the wavelet coefficient is larger than lambda, it is considered that the coefficient is mainly caused by signal, and this part of the coefficient is retained. Then the denoised signal is obtained by inverse wavelet transform of the processed wavelet coefficient.)

skin-depth
Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor with the current density being largest near the surface of the conductor, decreasing at greater depths. The electric current flows mainly at the "skin" of the conductor, between the outer surface and a level called the skin depth

说明：求根MUSIC算法，仿真中使用的阵列为均匀阵列，阵列数为8，接收信号数为2个，噪声为高斯白噪声。此算法是对经典MUSIC算法的改进，估计精确度更高。(Root MUSIC algorithm, the use of simulation for the uniform array of arrays, arrays of 8 to receive the signal number 2, noise is Gaussian white noise. This algorithm is the classical MUSIC algorithm, it is estimated that a higher accuracy.)
