- M2M4-该代码是经典的信噪比估计算法,用到了统计学中基于矩估计的思想,利用信号的2、4阶矩来估计接收信号的信噪比-M2M4-the code is the classic SNR estimation algorithm used in the statistical moment estimation based on the idea, the signal of 2,4-order moments to estimate the signal to noise ratio of the

- 当信噪比较大时,采用广义最小二乘法可能会出现多个局部收敛点,解决这个问题的方法可用多级最小二乘法,一般来说多级最小二乘法包含三级辨识过程。利用输入输出数据,通过多级最小二乘法,可分别求的辅助模型,过程模型和噪声模型的参数估计值。在高噪声的情况下,多级最小二乘法明显优于广义最小二乘法,其收敛点唯一。-When the signal noise ratio (SNR), and by use of the generalized least squares method may appear mor
