QPSK-BPSK-ASK-FSK and MSK Modulations that will help in modulation issues. It is experimental for a College Project and it may needs some corrections. Thx for understanding.

EQ design in matlab and presentation

Training based channel estimation

this file is about feedback linearization method.

说明：  基于DCT的水印图像matlab代码，主要是水印嵌入和水印提取两大主要部分(DCT-based image watermarking matlab code, mainly watermark embedding and watermark extraction are two main parts)

用c语言程序编写的一些算法程序，非常宝贵，吐血奉献。(gsdahhdfdsahdhfuj5r4wytryu56urteryertrt)

BPSK匹配滤波器的误码率统计。1.二进制PSK信号进过波形生成器，生成根升余弦信号 2.对信号加噪声 3.接受加噪信号后，匹配滤波 4.统计误码率(BPSK matched filter error rate statistics. 1 signal into a binary PSK waveform generator had to generate root raised cosine signal (2) of the signal plus noise 3. Accept the added noise signal, the matched filter 4. Statistical error rate)

Converting an image into blocks of 8 x 8 and apply DCT on any one of the blocks

说明：  对图片中字母数字识别，通过matlab实现(Recognition of letters and numbers in pictures)
