数字示波器 dds...编的还不错哦。。。可以实现三种波形，而且都是用rom表-Series of digital oscilloscopes dds ... still pretty good. . . Three waveforms can be achieved, and all the table with the rom

已知一个信道的信噪比，求出相应的误码率，matlab实现，很好用，很多场合需要计算这个。反过来也是可以的。-Known signal-to-noise ratio of a channel, the error rate is obtained, matlab realize, well used, need to calculate the number of occasions. The reverse is also possible.

自己用matlab与c接口方法编写的可以用matlab调用的C程序，实现Viterbi译码（软硬都可）。使用前在matlab里输入：mex - 文件名.c；-A c file can be used in matlab scr ipt to achive Viterbi Decoding (Error Control Coding) for both Hard Decision and Soft Decision.

用matalb实现OFDM系统，并且实现图片和音频的传输，可以借鉴-OFDM system with matalb achieve and realize the picture and audio transmission, can learn from
