图像处理，RS编码，纠错码这个单元对每个扰码后的传输数据帧,包括同 步字节进行截短的RS(204,188)编码.RS编码时, 在信息位前添加51字节的“0”再进入RS(255,239) 编码器,编码后再截去这些字节.RS(255,239)编码 -Image processing, RS coding, error correction code for each scrambling code of this unit after the transmission of data

给予matlab的JPEG压缩程序，包含原始压缩图片，程序对灰度bmp图片进行JEPG编码，压缩成以0101形式的编码。JPEG编码先把图象色彩RBG变成亮度Y和色度Cr、Cb，它利用人的视觉对色度不敏感的特点，减少一部分色度数据，以达到压缩。 JPEG采取多种编码方式，包含有行程编码(Run Length Coding)和哈夫曼(Huffman)编码，有很高的压缩比。在编码前，先对数据进行分块，离散余弦变换（DCT）及量化，保留能量大的低频信号，丢弃高频信号以达到压缩。-Given to th

The aim of this short workshop is to demonstrate the effectiveness of the JPEG encoding/decoding process using test data and test images. As explained in the lectures the major elements of the JPEG encoding process are the DCT, the non-uniform Quanti
