Quantifying the Eddy Feedback and the Persistence of the Zonal Index in an Idealized Atmospheric Model
(American Meteorological Society, 2009-12)
An idealized atmospheric model is employed to quantify the strength of the eddy feedback and the persistence of the zonal index. The strength of the surface frictional damping on the zonal index is varied, and an external ...
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 ...
The capacity of channels with feedback
(Institute of Electrical and Electronics Engineers, 2008-12)
In this paper, we introduce a general framework for treating channels with memory and feedback. First, we prove a general feedback channel coding theorem based on Massey's concept of directed information. Second, we present ...
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 ...
