采用正交频分复用（OFDM）调制的跳频系统仿真模块，利用Simulink工具箱搭建。可更改跳频跳速,跳频频率数，载波频率，跳频间隔，FFT运算长度,循环前缀位数等相关参数。信道采用瑞利多径衰落信道和高斯信道，相关参数也可更改。希望有一定的参考价值，也希望站长开通我的下载功能，ID：gly201,非常感谢！(A simulation on Hopping Frequency communication system based on the OFDM technique.)

介绍了多用户检测中遇到的相关问题及引起这些问题的原因，在此基础上提出自己的想法...(It introduce some related problems of MUD and the reasons which result in these problems.At the foundation of these reasons,I advance my personal ideas...)

帧内预测编码，已调试成功，垂直预测，其他预测方式可进行相应的修改(Intra prediction coding, debugging has been successful, the vertical prediction, other prediction methods can be amended accordingly)

去除adc采样信号基线程序，需要输入采样率，基线时刻等(trime base line)

神经网络可用于分类和回归，该程序使用MATLAB编写，用来进行信号分类(Neural networks can be used for classification and regression, the program use of MATLAB, used for signal classification)

直方图均衡化 直方图的均衡化可以使图像的像素灰度值动态范围变大，增强图像的对比度看起来更清晰。上图经过直方图均衡化方法处理后不再特别暗淡，其直方图反映出来的灰度的概率分布也相对比较均匀(Histogram equalization)

6lowpan的一个相关文章，很有用处的(6LoWPAN_The Wireless Embedded Internet，it is very good)
