利用matlab，ransac算法直线拟合(Use matlab, ransac linear fitting algorithm)

FDTD.m 程序包括程序相关变量的定义，网格的尺寸的划分，激励源的设置及基于FDTD的圆柱谐振腔迭代分析。其中通过改变空间离散度dr和采样点个数nmax，进行分析得出结论；且空间步长dt与dr有关，可得出空间步长对结果影响。(FDTD.m program includes the definition of program-related variables, set the meshing of size, the excitation source and the FDTD-based iterative analysis of cylindrical cavity. By changing the space in which the number of discrete sampling points of the dr and nmax, the conclusions drawn the analysis and space step dt and dr related space step can be drawn the impact on the results.)

回波抵消器中常用的几种自适应滤波算法有LMS, NLMS, RLS等算法。对现有主要算法的性能进行了分析，并对优缺点进行评价和比较。为了在收敛速度和运算量之间得到很好的折衷，对NLMS算法改进，得到了 PNLMS(Echo cancellation devices commonly used in adaptive filtering algorithm has several LMS, NLMS, RLS, such as algorithms. The main algorithm of the existing performance analysis, and evaluation and comparison of the advantages and disadvantages. For the convergence between computing speed and a good compromise on the NLMS algorithm improvements have been PNLMS)
