channel-coding_matlab
提高数据传输效率，降低误码率是信道编码的任务。信道编码的本质是增加通信的可靠性。但信道编码会使有用的信息数据传输减少，信道编码的过程是在源数据码流中加插一些码元，从而达到在接收端进行判错和纠错的目的(Improve the efficiency of data transmission, reduce the bit error rate is the channel coding task. The essence of channel coding is to increase the reliability of communication. But the channel coding can make data transmission of useful information is reduced, the channel coding process is to add some symbols in the source data stream, so as to achieve the purpose of erroneous judgment and correction at the receiver)

DCT-and-Image-Compression
DCT and Image Compression
In the JPEG image compression algorithm, the input image is divided into
8-by-8 or 16-by-16 blocks, and the two-dimensional DCT is computed for each
block. The DCT coefficients are then quantized, coded, and transmitted. The
JPEG receiver (or JPEG file reader) decodes the quantized DCT coefficients,
computes the inverse two-dimensional DCT of each block, and then puts the
blocks back together into a single image. For typical images, many of the
DCT coefficients have values close to zero these coefficients can be discarded
without seriously affecting the quality of the reconstructed image.
The example code below computes the two-dimensional DCT of 8-by-8 blocks
in the input image, discards (sets to zero) all but 10 of the 64 DCT coefficients
in each block, and then reconstructs the image using the two-dimensional
inverse DCT of each block. The transform matrix computation method is used.
