这是我自己编写的压缩感知图像重构的算法，直接观测原始信号（二维），最后重建(This is your perception image compression algorithm, direct observation review of the original signal, the reconstruction of a two-dimensional ） （ )

A local extremum of audio watermarking algorithm, matlab software watermark embedding and extraction operation, also gives some common attack method of audio watermarking attacks.

bch编码matlab 仿真,信道编码BCH码仿真，希望大家能用得上(bch encoding)

DES加密算法 matlab版本。 DES全称为Data Encryption Standard，即数据加密标准，是一种使用密钥加密的块算法，1976年被美国联邦政府的国家标准局确定为联邦资料处理标准（FIPS），随后在国际上广泛流传开来。(DES encryption algorithm matlab version. DES called the Data Encryption Standard, Data Encryption Standard, is a key block encryption algorithm, 1976 National Bureau of Standards has been determined for US federal government Federal Information Processing Standards (FIPS), then widely spread in the world come.)

涡度通量数据处理，坐标旋转之平面拟合坐标旋转，系数计算(Eddy flux data processing, the rotation of the coordinate plane fitted coordinate rotation, coefficient)

对采用双二进制信号脉冲的2电平PAM通信系统进行Monte Carlo仿真。输入二进制序列为{bn},预编码序列为{dn},幅度序列为｛an},相关序列为{cn}。将高斯噪声加到接收序列{bk}上去以形成检验信号的输入，并恢复这个数据。对1万个比特执行这个仿真，并在σ2=0.1,0.5,1时分别测量比特差错概率。用此概率跟无ISI的PAM的BER曲线作对比并进行分析。(Partial-Responsing Signal。)

一种计算时间周期的算法，可以长期使用，用于混沌相空间重构。(a new fangfa of kongjian didai)

This is the matlab code of multi class common spatial pattern.

该程序实现的事BPSK信号在两种信道下的仿真，分别是瑞利信道和高斯信道下的仿真，并对结果进行分析(The program implements thing BPSK signal two channel simulation, namely Rayleigh channel and Gaussian channel simulation, and the results were analyzed)

说明：  matlab实现： ①用乘同余数法产生白噪声 ②遗忘因子递推最小二乘参数估计（FFRLS）③M序列及逆M序列的产生④批处理最小二乘参数估计（LS）⑤产生m序列(Use by remnant produce white noise with law )
