Research into applying LDPC code theory, which is used for channel coding, to source coding has received a lot of attention in several research fields such as Distributed Source Coding.
In this paper a source coding problem with a fidelity criterion is considered. Matsunaga et al. constructed a lossy code under the conditions of a binary alphabet, a uniform distribution, and a Hamming measure of fidelity criterion.
We extend their results and construct a lossy code under the extended conditions of a binary alphabet, a distribution which is not necessarily uniform, and a fidelity measure which is bounded and additive and show that the code can achieve the optimal rate, rate-distortion function. |
