This paper, studies the comparative performance of a traditional and Concatenated coding schemes for transmission of digital data over a mobile communication channel. Traditional codes are effective for reliable transmission of information over hostile channel when the errors caused by the channel are statistically independent.

A new class of binary iteratively decodable codes with good decoding performance is presented. These codes, called braided block codes (BBCs), operate on continuous data streams and are constructed by interconnection of two component block codes. BBCs can be considered as convolutional (or sliding) version of either Elias' product codes or expander ...

The article discusses systematic cyclic linear block codes. A block code uses an encoder that accepts a block of message symbols, and generates a block of code word symbols at the output. This type is in contrast to a convolutional code when the encoder accepts a continuous stream of symbols and similarly generates a continuous encoded output stream. A

In block truncation coding (BTC), an image is segmented into n x n (typically, 4 x 4) nonoverlapping blocks of pixels, and a two-level (one-bit) quantizer is independently designed for each block. Both the quantizer threshold and the two reconstruction levels are varied in response to the local statistics of a block.

Publisher Summary This chapter focuses on block codes. Cyclic codes—an important class of codes—are used in many systems because they are easy to implement. Because a cyclic code is a linear code, it is decoded by making use of the syndrome. The syndrome polynomial is used for decoding cyclic codes instead of the syndrome vector.

ROI coding with separated code block
2005 International Conference on Machine Learning and Cybernetics, 2005ROI coding can effectively improve the subjective quality of image. There are some known disadvantages in existing ROI coding methods. This paper presents a new ROI coding method based code block selection mechanism. The method is to separate ROI and background data, and to place them to individual code blocks, ROI code block and background code block,

Block truncation coding with entropy coding
IEEE Transactions on Communications, 1995Block truncation coding (BTC) is a simple and fast image compression algorithm which achieves a constant bit rate of 2.0 bits per pixel. The method is however suboptimal. We propose a modification of BTC in which the compression ratio is improved by coding the quantization data and the bit plane by arithmetic coding with an adaptive modelling scheme ...

From the work of Shannon one knows that it is possible to signal over an error-making binary channel with arbitrarily small probability of error in the delivered information. The effects of errors produced in the channel are to be eliminated, according to Shannon, by using an error correcting code. Shannon's proof that such codes exist does not provide
