这是国标数字电视地面传输标准里信道编解码器的MATLAB程序，用的是LLR-BP的解码算法，请大家指正。另有根据国标生成的生成矩阵和校验矩阵稍后传上来(This is the national standard of digital TV terrestrial transmission standard in channel codec MATLAB program, using the LLR-BP decoding algorithm, please correct me. Otherwise in accordance with GB-generated matrix and calibration matrix generation later Chuan-up)

很有用的MATLAB图例,里面有十几种,包含图片,希望能帮到你.(MATLAB useful Legend, which has a dozen, including pictures, hope to help you.)

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)

Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as shown by Figure 4. First, since the incoming waveform is suppressed carrier in nature, coherent detection is required. The methods by which a phase-coherent carrier is derived from the incoming signal are termed, carrier recovery, and will be covered first.
