Channel-optimized quantum error correction
We develop a theory for finding quantum error correction (QEC) procedures which are optimized for given noise channels. Our theory accounts for uncertainties in the noise channel, ...

Knuth's balanced codes revisited
Abstract--In 1986, Don Knuth published a very simple algorithm for constructing sets of bipolar codewords with equal numbers of "1"s and "01"s, called balanced ...

Asymmetric multilevel diversity coding and asymmetric Gaussian multiple descriptions
We consider the asymmetric multilevel diversity (A-MLD) coding problem, where a set of 2 K 1 information sources, ordered in a decreasing level of importance, is encoded into K me...

Correcting limited-magnitude errors in the rank-modulation scheme
We study error-correcting codes for permutations under the infinity norm, motivated the rank-modulation scheme for flash memories. In this scheme, a set of n flash cells are combin...

Tunstall code, Khodak variations, and random walks
A variable-to-fixed length encoder partitions the source string into variable-length phrases that belong to a given and fixed dictionary. Tunstall, and independently Khodak, desig...

Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

On the optimum distance profiles about linear block codes
In this paper, for some linear block codes, two kinds of optimum distance profiles (ODPs) are introduced to consider how to construct and then exclude (or include) the basis codewo...

Generalizing capacity: new definitions and capacity theorems for composite channels
We consider three capacity definitions for composite channels with channel side information at the receiver. A composite channel consists of a collection of different channels with...
