OFDM SYSTEM SIMULATION SORCE

matlab图像处理领域类的一种常用算法。对初学者有很大的帮助(matlab image processing class, a common algorithm. Very helpful for beginners)

说明：  直接序列扩频的一个例子，对学习这方面知识，和编程都有很好的帮助(An example of direct-sequence spread spectrum, to learn that knowledge, and programming are very helpful)

用于求一个信号的斜率，通过构造一个滤波器来实现的，绝对正确。(For seeking the slope of a signal, to be achieved by constructing a filter, absolutely correct.)

可以实现ofdm的LS信道估计，并与未采用估计时进行比较(The LS can ofdm channel estimation, and with no comparison with estimates)

说明：  电机的仿真，其中包括电机的建模及各种算法的设计，其中主要使用闭环控制来实现。(motor simulation, including electrical modeling algorithms and the design, mainly use closed-loop control to achieve.)

完整的OFDM仿真Matlab程序。从发射机到接收机。(Complete OFDM simulation Matlab. From transmitter to receiver.)

imnoise2 预加噪声 matlab code(imnoise2 pre-plus noise)

自编奇异值MATLAB程序，利用奇异值去除信号噪声。以供参考。(Editing the singular value MATLAB, using the singular value to remove noise signal. For your reference.)

说明：  使用matlab的霍夫曼编码简单实例，输入包括给定概率表和字符串输入，输出包括编码后的结果和，解码后结果(Huffman encoding matlab use a simple example, the input comprising a given probability table and string input, output, including the results of encoded and decoded Results)
