在matlab平台下开发的对手写数字识别代码，(In matlab platform developed under the code of handwritten numeral recognition,)

说明：  这是基于周期图改进的welch的功率谱估计，这种方法是在经典周期图的基础上改进而来的，效果很不错(This is based on the improved welch periodogram power spectral estimation, this method is based on the classical periodogram improvement came, the effect is very good)

FHSS transmitter and receiver in matlab

Created OFDM coder and decoder for baseband signal transmission in 2K mode without error correction capabilities.

描述在matlab环境下，bch的误码率，仿真给出了在编码情况下的误码比较，可以清楚的得出bch码的编码增益。(Describes the matlab environment, bch the BER, the simulation is given in case of error in the code comparison can be drawn clearly bch code coding gain.)

包括8PSK和18QAM调制程序，复信号，带成型滤波器。程序简单易行，绝对可靠。(8PSK and 16QAM signal。)

基于matlab的一个小程序，用GUI可能简单些(maybule you should sese)

sorce code for line flow

简单的使用*.ffe文件返回值计算一维距离像的小程序(Simple to use* .ffe file returns the value calculated the one-dimensional image of the applet)

先将47168bit的宿主音频等步长分段,分为1000段，然后混沌序列选择其中的102段，对每段进行3及小波分解，挑选出绝对值最大的系数，运用嵌入公式。(47168bit first step of the host audio sub-divided into section 1000, and then select one of the 102 chaotic sequence segment, on each piece of a 3 and wavelet decomposition, the largest absolute value coefficients selected using the embedded formula.)
