Genetic decoding of linear block codes

Proceedings of the 1999 Congress on Evolutionary Computation-CEC99 (Cat. No. 99TH8406), 2003
This paper investigates the application of genetic algorithms to the decoding problem of error-correcting codes. The basic operations of crossover, mutation and selection are appropriately defined for the decoding problem of binary linear block codes without the knowledge of any algebraic structure.

Linear Block Codes

1998
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 ...

Linear block codes for error detection

IEEE Trans. Inf. Theory, 2020
Summary: The probability of undetected error of linear block codes for use on a binary symmetric channel is investigated. Upper bounds are derived. Several classes of linear block codes are proved to have good error-detecting capability.

On importance sampling for linear block codes

IEEE International Conference on Communications, 2003. ICC '03., 2004
We introduce an importance sampling scheme for linear block codes with message-passing decoding. This novel scheme overcomes an existing difficulty in the IS practice that requires codebook information. Experiments show large IS gains for single parity-check codes and short-length block codes.

Concentration of magnetization for linear block codes

2008 IEEE International Symposium on Information Theory, 2008
We consider communication over the binary erasure and the binary additive white gaussian noise channels using fixed linear block codes and also appropriate ensembles of such codes. We show concentration of the magnetization over the channel realizations and also over the code ensembles. The result has various implications.

The (d,k) subcode of a linear block code

IEEE Transactions on Information Theory, 1992
Summary: A simple technique employing linear block codes to construct \((d,k)\) error-correcting block codes is considered. This scheme allows asymptotically reliable transmission at rate \(R\) over a BSC channel with capacity CBSC provided \(R\leq C_{d,k}-(1+CBSC)\), where \(C_{d,k}\) is the maximum entropy of a \((d,k)\) source.

Linear Block Codes

2020
As usual, in this chapter we consider that p denotes a prime number, q is a prime power and \({\mathbb F}_{q}\) is the finite field with q elements. We begin by defining the general concept of a code over \({\mathbb F}_{q}\); after this, we present the concept of a linear code that is the more important class of codes in coding and information theory ...

Linear Block Codes

1999
Some elementary concepts of block codes are introduced in Chapter 1. In general, it is known that the encoding and decoding of 2 k codewords of length n can be quite complicated when n and k are large unless the encoder has certain special structures. In this chapter, a class of block codes, called linear block codes, is discussed.

New ternary and quaternary linear block codes

IEEE Transactions on Information Theory, 1996
Summary: We present several new ternary and quaternary codes found with a heuristic search procedure, originally proposed by the authors to find good binary codes, and which is based on combinatorial optimization.
