Abstract :
In this paper, we study the design of causal anytime codes for transmission over symmetric discrete memoryless channel. In our earlier work [1], we proposed an anytime transmission scheme which is based on unequal error protection using Luby transform codes (UEP-LT) and sequential belief propagation (BP) decoding. In this paper we extend our previous result by providing an analysis on the proposed scheme. In particular, an upperbound on the end-to-end distortion of the anytime transmission scheme is derived.
