粒子滤波算法关于目标跟踪的源代码，有注释可以相互学习下。(The source code of the particle filter algorithm for target tracking, the comment can learn from each other.)

主要根据回声路径的改变来判断是否发生了双端通话，对研究算法的同学具有一定的参考价值。(A double-ended conversation about the detection of foreign literature, mainly based on changes in the echo path to determine whether there has been double-ended conversation, students study algorithm has a certain reference value.)

可以自动调整matlab figure的尺寸，使众多图保持一致，用于论文中图的调用比较方便，更加美观(Matlab figure can automatically adjust the size, so that many figure consistent call graph paper for more convenient, more beautiful)

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 more local convergence point, the way of solving this problem can be used multistage least squares method, and generally multistage least squares method includes three identification process. Using input/output data, through the multistage least squares, respectively for the auxiliary model, process model and noise model parameter estimation. In the high noise, multistage least squares method is obviously superior to the generalized least squares method, and its convergence point only.)
