Abstract

Codes with decomposable structure allow the use of multistage decoding procedures to achieve suboptimum bounded-distance error performance with reduced decoding complexity. This correspondence presents some new decomposable codes, including a class of distance-8 codes, that are constructed based on the |a+x|b+x|a+b+x| construction method. Some existing best codes are shown to be decomposable and hence can be decoded with multistage decoding.

Suboptimum decoding of block codes

Shu Lin, Tadao Kasami

This paper investigates a class of decomposable codes, their distance and structural properties. it is shown that this class includes several classes of well known and efficient codes as subclasses. Several methods for constructing decomposable codes or decomposing codes are presented. A two-stage soft decision decoding scheme for decomposable codes, their translates or unions of translates is devised. This two-stage soft-decision decoding is suboptimum, and provides an excellent trade-off between the error performance and decoding complexity for codes of moderate and long block length.

Suboptimum decoding of decomposable block codes

T. Takata, Y. Yamashita, Toru Fujiwara +2 more

To decode a long block code with a large minimum distance by maximum likelihood decoding is practically impossible because the decoding complexity is simply enormous. However, if a code can be decomposed into constituent codes with smaller dimensions and simpler structure, it is possible to devise a practical and yet efficient scheme to decode the code. This paper investigates a class of decomposable codes, their distance and structural properties. It is shown that this class includes several classes of well-known and efficient codes as subclasses. Several methods for constructing decomposable codes or decomposing codes are presented. A two-stage (soft-decision or hard-decision) decoding scheme for decomposable codes, their translates or unions of translates is devised, and its error performance is analyzed for an AWGN channel. The two-stage soft-decision decoding is suboptimum. Error performances of some specific decomposable codes based on the proposed two-stage soft-decision decoding are evaluated. It is shown that the proposed two-stage suboptimum decoding scheme provides an excellent trade-off between the error performance and decoding complexity for codes of moderate and long block length.>

clidean-Space e inimurn-Distance Decodi

G. David Forney

It is shown that multistage generalized minimum- distance (GMD) decoding of Euclidean-space codes and lattices can provide an excellent tradeoff between performance and com- plexity. We introduce a reliability metric for Gaussian channels that is easily computed from an inner product, and prove that a multistage GMD decoder using this metric is a bounded- distance decoder up to the true packing radius. The effective error coefficient of multistage GMD decoding is determined. Two simple modifications in the GMD decoding algorithm that drastically reduce this error coefficient are proposed. It is shown that with these modifications GMD decoding achieves the error coefficient of maximum-likelihood decoding for block codes and for generalized Construction A lattices. Multistage GMD decod- ing of the lattices Dg, Ea, K12, BW16, and A24 is investigated in detail. For 1<12,BW~, and A24, the GMD decoders have considerably lower complexity than the best known maximum- likelihood or bounded-distance decoding algorithms, and appear to be the most practically attractive decoders available. For high-dimensional codes and lattices (2 64 dimensions) maximum- likelihood decoding becomes infeasible, while GMD decoding algorithms remain quite practical. As an example, we devise a multistage GMD decoder for a 128-dimensional sphere packing with a nominal coding gain of 8.98 dB that attains an effective error coefficient of 1 365 760. This decoder requires only about 400 real operations, in addition to algebraic errors-and-erasures decoding of certain BCH and Hamming codes. It therefore ap- pears to be practically feasible to implement algebraic multistage GMD decoders for high-dimensional sphere packings, and thus achieve high effective coding gains.

Performance of Error-Control Codes

Richard E. Blahut

In any engineering discipline, one looks for methods of solving a given class of problems and then for methods of quantifying the performance and complexity of those solutions. Accordingly, in this chapter, we shall study performance in terms of the composition structure of block codes, and the probabilities of decoding error and of decoding failure. Later, after satisfactory methods are in hand, one turns to questions of optimality. Are these methods the best methods, and if not, in what ways and by how much are they inferior? To answer such questions, one needs to know how good are the known codes and how good are the best possible codes. Generally, we cannot answer either of these questions satisfactorily. Although for any given rate and blocklength, not too small, the best possible code is not known, a number of bounds are known – bounds beyond which no codes can exist, and bounds within which codes are sure to exist. We shall give some such bounds on the best possible codes later in this chapter. Knowledge of these bounds can deepen our understanding of the subject. Weight distributions of block codes If a linear block code has a minimum distance d min , then we know that at least one codeword of weight d min exists. Sometimes, we are not content with this single piece of information; we wish to know how many codewords have weight d min , and what are the weights of the other codewords.

On the construction of a class of majority-logic decodable codes

Tadao Kasami, Shu Lin

The attractiveness of majority-logic decoding is its simple implementation. Several classes of majority-logic decodable block codes have been discovered for the past two decades. In this paper, a method of constructing a new class of majority-logic decodable block codes is presented. Each code in this class is formed by combining majority-logic decodable codes of shorter lengths. A procedure for orthogonalizing codes of this class is formulated. For each code, a lower bound on the number of correctable errors with majority-logic decoding is obtained. An upper bound on the number of orthogonalization steps for decoding each code is derived. Several majority-logic decodable codes that have more information digits than the Reed-Muller codes of the same length and the same minimum distance are found. Some results presented in this paper are extensions of the results of Lin and Weldon [11] and Gore [12] on the majority-logic decoding of direct product codes.

A bounded-distance decoding algorithm for the Leech lattice, with generalizations

G. David Forney

An algorithm is given that decodes the Leech lattice with not much more than twice the complexity of soft-decision decoding of the Golay code. The algorithm has the same effective minimum distance as maximum-likelihood decoding and increases the effective error coefficient by less than a factor or two. The algorithm can be recognized as a member of the class of multistage algorithms that are applicable to hierarchical constructions. It is readily generalized to lattices that can be expressed in terms of binary code formulas, and in particular to construction B lattices.>
