The weight distribution is an indispensable parameter in the performance evaluation of a code because of its importance in the analysis of the codes characteristics. Since the amount of computation needed to determine the overall weight distribution of a code usually depends on the number of data po

β¦ Synopsis
For a linear code over GF (q) we consider two kinds of ''subcodes'' called residuals and punctures. When does the collection of residuals or punctures determine the isomorphism class of the code? We call such a code residually or puncture reconstructible. We investigate these notions of reconstruction and show that, for instance, selfdual binary codes are puncture and residually reconstructible. A result akin to the edge reconstruction of graphs with sufficiently many edges shows that a code whose dimension is small in relation to its length is puncture reconstructible.

Soft decision decoding is a decoding method which can cut the decoding error probability as compared with hard decision decoding by utilizing the channel measurement information effectively. In this paper, a new soft decision decoding method by which decoding operations can be efficiently carried ou

Deterministic analysis is becoming increasingly popular to study the theoretical mechanisms of modulation, as opposed to the classical noise-shaping approach. This paper gives an overview of its application to the speciΓΏc problem of signal reconstruction. Once an input signal has been processed thro
The paper addresses the microplane model in the context of localization analysis. Capable of reproducing experimental results of concrete specimens, the microplane model includes anisotropic damage in a natural and conceptually simple and explicit way. However, the efficiency of former microplane im
