On the Structure of Optimal Real-Time Encoders and
Decoders in Noisy Communication

The
output of discrete-time Markov source must be encoded into a sequence of
discrete variables. The encoded
sequence is transmitted through a noisy channel to a receiver that must attempt
to reproduce reliably the source sequence. Encoding and decoding must be done in real-time and the
distortion measure does not tolerate delays. We determine the structure of real-time encoding and
decoding strategies that jointly minimize an average distortion measure over a
finite horizon. We extend our
results to the real-time broadcast problem and a real-time variation of the
Wyner-Ziv problem.
