说明：  利用Matlab编写求取4级移位寄存器的M序列 设初始序列为:1 1 1 1 通过一个四级的移位寄存器,其中在第三级有负反馈(一个模二加法),即将序列的第三位和第四位相加(如序列1 1 1 1经移位寄存器第一次移位后为0 1 1 1)的值再赋到第一位. 序列的周期为16.(The use of Matlab to prepare to strike four of the M shift register sequence based initial sequence as follows: 1 1 1 1 4 through a shift register, which in the third grade there is negative feedback (one-mode two adder), the upcoming series third and fourth combined (such as the sequence 1 1 1 1 by the shift register after the first shift for the 0 1 1 1) the value given to the first again. The cycle sequence was 16.)

实现基本的PCM编译码功能，函数简单，程序可行(PCM encoding and decoding functions to achieve the basic function is simple, practical procedures)

智能控制，智能优化，刘金坤，很多的应用程序，机器人控制的好好学学。(intellgent control and design,liujinkun many demos,especially in robotic control)

文件中包含将车轮和cameraman图像进行动画演示，两者交替出现，可将颜色和交替时间等参数进行改动以达到个人的需求。(File contains the wheel and the cameraman images animated demo, alternating between the two may be the turn of time, such as color and changes the parameters in order to achieve the needs of individuals.)

提出了一个采用(2,1,7)卷积码+QPSK的中频调制解调方案,并在Xilinx公司的100万 门FPGA芯片上实现了该系统。该系统在信噪比SNR为6dB左右时可实现速率超过1Mbit/s、误码率 小于10-5的数据传输。 (Proposed a use of (2,1,7) convolutional code+ QPSK modulation and demodulation of the IF program, and in Xilinx' s FPGA chip one million on implementation of the system. The system SNR to 6dB signal to noise ratio at about the rate may achieve more than 1Mbit/s, less than 10-5 bit error rate of data transmission.)

此程序用C语言用哈夫曼编码法实现了对英文的压缩与解压缩，是C语言编程一个比较经典的例子(this program in C language with Huffman coding method to achieve the right English compression and decompression, the C programming language is a classic example)
