This file contains codes for simulating BPSK modulation with Monte Carlo methos. it is so useful for calculating BER in communication systems.

Channel Estimation in Wavelet Transform using Harr filter (4-levels)

粒子群优化工具箱，采用Matlab编写的PSO程序工具箱(Development Notes for psopt toolbox Future plans (in no particular order): * Performance improvement: Automatically check for existence of constraints, skip boundary-checking if unconstrained. * Performance improvement: Automatically vectorize fitness functions supplied by user, if not already vectorized. * Performance improvement: Detect and eliminate dependent (i.e. redundant) linear constraints. * Performance improvement: Automatically choose "penalize" versus "soft" constraint handling method based on type of constraints in problem. If any equality constraints exist, using "penalize", otherwise default to "soft". If "soft", automatically switch to "penalize" if more than a given percentage of particles (initial or interim) are infeasible. * Feature: An output function defined by options.OutputFcns that can save current swarm state in a file which can be reloaded later as a problem structure, in case of a system crash. * Feature: Implement multiobjective optimization option)

说明：  这是一种不错的牛顿算法，是老外编的，大家看看吧～(This is a good Newton algorithm, is a foreigner series, we look at it ~)

Mersenne Twister随机数发生器（Mersenne Twister generator,MTG for short）是Makoto Matsumoto于1998年对TGFSRG(旋转广义反馈移位寄存器发生器)的更进一步改进。(Mersenne Twister random number generator (Mersenne Twister generator, MTG for short) is Makoto Matsumoto in 1998 TGFSRG (rotation generalized feedback shift register generator) is further improved.)

自适应滤波算法与实现，有些matlab的实现方法，一本不错的书(A book for adaptive digital filter and implement, and this book is very good)

本程序是一个用短时傅立叶变换实现的心音时间、频率分析(This program is a short-time Fourier transform implemented with the heart sound time frequency analysis)

说明：  实现用bt法，welch法，周期图法，burg法对信号进行滤波(Achieved with the bt method, welch method, periodogram, burg method of signal filtering)
