Low density codes achieve the rate-distortion bound
Abstract: We propose a new construction for low-density source codes with multiple parameters that can be tuned to optimize the performance of the code. In addition, we introduce a...

Myopic Coding in Wireless Networks
Abstract -We investigate the achievable rate of data transmission from sources to sinks through a multiple-relay network. We study achievable rates for omniscient coding, in which ...

Practical Interleavers for Systematic Repeat-Accumulate Codes
In this paper we design interleavers for systematic repeat-accumulate (RA) codes. The new interleavers, which we call L-type and modified L-type interleavers, are deterministic, ...

Improving Semistatic Compression Via Pair-Based Coding
In the last years, new semistatic word-based byte-oriented compressors, such as Plain and Tagged Huffman and the Dense Codes, have been used to improve the efficiency of text retri...

Linear Joint Source-Channel Coding for Gaussian Sources through Fading Channels
Abstract— We consider the linear coding of a discrete memoryless Gaussian source transmitted through a discrete memoryless fading channel with additive white Gaussian noise (AWGN)...
