On asymmetric error-correcting codes

Creator:

Cunningham, Robert Stephen

Abstract:

Historically, coding theory has dealt with binary codes correcting symmetric errors, in which errors are made in both 0 and 1 bits with equal likelihood. Within the past ten years, some study has been made of asymmetric codes, under the assumption that the only errors which occur are errors in...

Unidirectional error correcting/detecting codes

Creator:

Lin, Der Jei

Abstract:

An extensive theory of symmetric error control coding has been developed in the last few decades. The recently developed VLSI circuits, ROM, and RAM memories have given an impetus to the extension of error control coding to include asymmetric and unidirectional types of error control. The maximal numbers of unidirectional...

New bounds and constructions for error control codes

Creator:

Al-Darwish, Nasir Ali

Abstract:

The bulk of the theory on error control codes has been developed under the fault assumption of random (symmetric) errors, where 1 → 0 and 0 → 1 errors are equally likely. In the past few years, several applications have emerged in which the observed errors are highly asymmetric. This...
