Chapter 2 gives a brief review of linear block codes. The goal is to provide the essential background material for the development of trellis structure and trellis-based decoding algorithms for linear block codes in the later chapters. We mainly present the basic concepts of encoding and decoding of linear block codes and state some facts without ...

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 ...

Minimal trellises for block codes
IEEE Transactions on Information Theory, 1988Basic concepts in the study of trellises of block codes are defined. It is shown that minimal proper trellises exist for all block codes. Bounds on the sizes of such trellises are established. These bounds are shown to be exact for maximum distance separable codes and nearly so for perfect codes.

In this chapter, we will explain the construction of linear block codes. Since linear block codes are vector subspaces, we advise to the reader to study Chap. 1 before proceeding to Chap. 2. Without the knowledge of basic concepts of linear algebra, such as groups, fields, vector spaces, and subspaces, it is difficult to comprehend the philosophy ...

Synchronization methods for block codes
IEEE Transactions on Information Theory, 1962Summary: Efficient use of block codes to communicate over a telemetry channel is dependent upon the knowledge of the instants, in time, that one code waveform, or code word, ends and the succeeding waveform begins. This word synchronization is the subject of concern in this paper.

The traditional Shannon theory focuses almost exclusively on block coding techniques, that is, source and channel codes that consist of mapping blocks of nonoverlapping data into blocks of encoded data. Such codes (1) have undesirable probabilistic properties such as loss of stationarity and ergodicity, (2) do not include several practical ...
