对从金属棒材中提取的超声缺陷信号经过自适应滤波以后的极坐标显示图(polar graph of ultrasonic defect signal)

alphabet recognization, a simplified version only to detect few numerical pronunciations

The report contains sourses and pictures. The program contains two sources. The first one computes the Wigner Distribution (second-order). The second one computes the Wigner Distribution with Choi-Williams filtering.

这个程序是属于阵列信号处理范畴的，利用TLS-ESPRIT算法进行测向，是一个子程序，阵列形式可以是任意的，可以设置接收信号的模型，然后运用此算法测向。(This program belongs to array signal processing areas, the use of TLS-ESPRIT direction finding algorithm is a subroutine, the array can be any form, you can set a model the received signal, and then use this algorithm finding.)

这是自己编写的关于OMP的matlab程序，欢迎借鉴，谢谢(This is a matlab program, I have written about the OMP welcome to learn from, thank you)

说明：  仿真了FM信号产生和调制的过程，方法简单，内容详尽，已经过调试。(Simulation of the FM signal and modulation process, the method is simple, detailed, has been testing.)

OFDM的完美运行仿真程序，主程序较长，但是有每一句的解释，是学习matlab的好例子(OFDM simulation program running perfectly, the main program is longer, but the interpretation of every sentence is a good example to learn matlab)
