Ddataanalysis

用matlab实现一个维纳滤波器，用于滤除噪声。(Using matlab to achieve a Wiener filter for filtering noise.)

This MATLAB implementation computes a correspondence between two shapes based on ant colony optimization (ACO). The input shapes can be either two 2D contours (open or closed) or two arbitrary sets of 2D points. The algorithm is described in detail in:

说明：  此为MATLAB写的关于2DPSK调制解调的程序并且通过验证可以实现，程序对2DPSK的算法都有相应的程序(This is written in MATLAB on 2DPSK modem to verify the procedure can be achieved through the procedures of the algorithm 2DPSK procedures have corresponding)

微带多模谐振器的谐振频率的提取程序，就是在已知线宽，线长和介质基底的情况下如何计算得到其多个谐振频率。学习多模谐振器数值分析的同学可以参考一下。(Multi-mode microstrip resonator resonance frequency extraction procedure is known in the case of the line width, line length and the dielectric substrate to which a plurality of resonance frequencies calculated. Learning multimode resonator numerical analysis of the students can refer to.)
