matlab节点电压法算电路电压，很简单的学习资料(matlab calculating circuit voltage of the node voltage method, a very simple learning materials)

本人用matlab做的viterbi译码及编码程序，很详细，可供初学者使用(I use matlab to do viterbi decoding and encoding procedures is very detailed, for beginners)

灰色关联度分析及灰色预测，本函数是根据GM(1,1)模型所编写而成的，大致思想是： % 对于一些有噪声的数据，通过一次累加生成，使其变为较为有规律性的数据，通过对于该数据的预测从而实现对于原数据的预测。(Grey correlation analysis and grey prediction)

二相编码信号的产生以及频谱分析，可以产生7位、11位、13位典型编码信号以及13位bark码的频谱图，通过仿真可用(Two-phase coded signal generation and spectrum analysis, can produce 7, 11 and 13 typically coded signals and 13 yards of bark frequency spectrum, through the simulation can be used)

小球撞壁变色的matlab程序，以一图片为背景，小球随机移动，小球撞壁时颜色改变(The ball hit the wall discoloration matlab program)

在阵列信号处理中，信号源个数的估计是一个重要问题，文献和代码给出了基于随机矩阵理论的阵列信号个数的非参检测。(In array signal processing, the estimate of the number of signal source is an important issues, documentation and code give an non-parametric detection of array signal number based on random matrix theory.)

雷达系统仿真类的，天线波束中，产生一个线性阵列信号。(Radar simulation system and the like, the antenna beam, the signal to generate a linear array.)

is95系统的基带仿真程序。自己可以去调试，(IS95 baseband system simulation program. They are able to debug,)

使用matlab仿真OFDM。其中描述了OFDM的基本原理，含详细的公式推导过程。在文章最后附有matlab代码，并且有仿真结果可参考。(Matlab simulation using OFDM. Describes one of the basic principles of OFDM, with a detailed formula derivation process. At the last article with matlab code, and have the simulation results can be found.)

对snake连接程序进行改进，使得边缘提取后断续的边缘能够完成连接。(Linker on the snake to improve so that the edge of edge detection can be completed after the intermittent connection.)
