this matlab code reads the data text files UCI Spoken Arabic Digits and save the results in a mat file which user can easily use.

this is about channel coding

matlab中用小波变换求故障距离的程序，精度高(xiaobo qiu gu zhang juli)

基于K-L变换下的人脸检测程序，用matlab编写的(KL transform based face detection under the program, using matlab)

实现了PCM编码->基带码型转换（NRZ to HDB3）->QPSK调制->高斯信道->QPSK解调->基带码型反转换（HDB3 to NRZ）->PCM解码。同时给出了误码率曲线。(Achieve a PCM coding-> Baseband code converter (NRZ to HDB3)-> QPSK Modulation-> Gaussian channel-> QPSK demodulator-> anti-baseband conversion pattern (HDB3 to NRZ)-> PCM decoding. Also shows the BER curves.)

it is useful for my studies
