OFDM，QPSK调制下仿真程序，包括信道编解码，调制解调，上下采样(OFDM, QPSK modulation simulation program, including channel coding and decoding, modulation and demodulation, the upper and lower sampling)

这是我们参加2011年全国大学生数学建模大赛，做A题的论文和matlab程序，当年获得国奖。 利用此程序可以进行污染源位置反演计算，以及其他类似服从高斯扩散模型的源项反演。 计算量小，简单易懂。(Detect of Pollution source in city.2011 China Undergraduate Mathematical Contest in modeling Q_A.)

通过PCM脉冲编码调制、恢复、量化、译码等过程实现A律十三线折线近似的仿真(Through the PCM pulse code modulation, recovery, quantification, A-law decoding process to achieve such a line similar to the simulation of thirteen lines)

一个gui案例，可以产生随机的双色球数据，免去你的烦恼(For a gui case can produce random ShuangSeQiu data, and turn away your troubles)

计算微分方程系统的Lyapunv exponent,在非线性动力学和有关混沌的研究中非常有用。(calculated differential system Lyapunv exponent, Nonlinear Dynamics and Chaos in the study very useful.)

本子程序用于计算单个球形粒子米散射参数：吸收、散射、消光效率、不对称因子。 参见尹宏：《大气辐射学基础》P53―59，P92―96，P101―121。( Book program for calculating the single spherical particle scattering parameters meter: absorption, scattering, extinction efficiency and asymmetry factor. See Yin Wang: Fundamentals of Atmospheric Radiation )

这是我用MATLAB做的计算器，只供参考(calutor)

说明：  详细介绍数字信号处理及MATLAB应用实现的书籍(Detailed application of digital signal processing and MATLAB realization of the books)

matlab小波变换源代码，供广大研究者学习(matlab wavelet transform source code, for the majority of researchers to learn)

Phase-shift keying (PSK) is a method of digital communication in which the phase of a transmitted signal is varied to convey information. There are several methods that can be used to accomplish PSK.
