This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB

一个聚类程序，基于贝叶斯最小错误率的判别，效果挺好的。(A clustering procedure, based on Bayesian minimum error rate of the discriminant, the effect quite good.)

In this paper, a new approach based on the R, filtering is presented for speech enhancement. This approach differs from the traditional modified Wiener

基于Matlab的FIR数字滤波器，利用MATLAB信号处理工具箱中提供的基于滤波器设计方法的工具函数，采用窗设计法，用switch选择窗的类型:1、矩形窗2、汉宁窗3、汉明窗4、布拉克曼窗。(Based on the Matlab FIR digital filters, use of Matlab signal processing of the kit provides design method based on filter tool function, the window design method, choose the type of window with switch: 1, rectangular window 2, han ning window 3, han Ming window 4, braque window). )

角度和延时估计，里面一共5个小程序，已经写成函数形式，亲测好用(to estimate angle and time delay in array signal processing)

相位移频键控的维特比解码 64状态 比较 回溯(QPSK viterbi decode)

粒子追踪测速的相关程序，所使用的算法为最邻近原则，通过粒子链表形成匹配(Particle tracking velocimetry procedures, the algorithm used for the nearest neighbor principle formed by particles linked list match)
