Non-binary distributed arithmetic coding

Abstract

The development of wireless sensor networks has inspired great research interest in the design of distributed source coding(DSC) schemes. Among various DSC schemes, distributed arithmetic coding (DAC) is an attractive option due to its low encoding complexity as well as its good performance at short block lengths. Since DAC has only been proposed for binary sources to date, in this paper we propose two non-binary DAC schemes and investigate their performance and complexity via computer simulations.
