Consider a source network in which a finite alphabet source X = {Xi}i=0 infin is to be encoded and transmitted, and another finite alphabet source Y = {Xi}i=0 infin correlated with X is available only to the decoder as side information. Traditionally

Linear codes for a coding problem of correlated sources are considered. It is proved that we can construct codes by using low-density parity-check (LDPC) matrices with maximum-likelihood (or typical set) decoding. As applications of the above coding

Coding problems for correlated information sources were first investigated by Slepian and Wolf. They considered the data compression system, called the SW system, where two sequences emitted from correlated sources are separately encoded to codewords

The channel in the intensity modulation-direct detection (IMDD) system, which is one of the typical optical communication systems, can be modeled as a Z-channel, where only “1-to-0” errors are produced. Consequently, by applying the all-unidirect

Quantum communication with a nonsymmetrical set of three states is considered. Some results obtained from numerical computation are presented. A model for quantum detection called "near optimum", similar to the binary case, is studied. Calculations o

This paper presents three new maximum likelihood decoding (MLD) algorithms for linear codes over Z-channel, which are much more efficient than conventional exhaustive algorithms. In the proposed algorithms, their complexities are reduced by employing
