Tradeoffs between the excess-code-length exponent and the excess-distortion exponent in lossy source coding
Lossy compression of a discrete memoryless source (DMS) with respect to a single-letter distortion measure is considered. We study the best attainable tradeoff between the exponent...

Structure of non-binary regular ldpc cycle codes
In this paper, we study non-binary regular LDPC cycle codes whose parity check matrix has fixed column weight 2 and fixed row weight d. We prove that the parity check matrix of ...
