A Simple Converse of Burnashev's Reliability Function
(Institute of Electrical and Electronics Engineers, 2009-06)
In a remarkable paper published in 1976, Burnashev determined the reliability function of variable-length block codes over discrete memoryless channels (DMCs) with feedback. Subsequently, an alternative achievability proof ...
Unequal Error Protection: An Information-Theoretic Perspective
(Institute of Electrical and Electronics Engineers, 2009-11)
An information-theoretic framework for unequal error protection is developed in terms of the exponential error bounds. The fundamental difference between the bit-wise and message-wise unequal error protection ( UEP) is ...
