We determine the rate region of the quadratic Gaussian two-encoder source-coding problem. This rate region is achieved by a simple architecture that separates the analog and digital aspects of theâ€¦ (More)

We consider a problem in which two encoders observe different components of a memoryless, Gaussian, vectorvalued source. The encoders separately communicate with a decoder, which attempts toâ€¦ (More)

We consider block codes whose rate converges to the channel capacity with increasing blocklength at a certain speed and examine the best possible decay of the probability of error. For discreteâ€¦ (More)

Moderate deviation behavior of coding for discrete-memoryless channels is investigated. That is, we consider block codes whose rate converges to the channel capacity from below with increasing blockâ€¦ (More)

The problem of deriving refined bounds on the sub-exponential factor in the random coding bound for discrete memoryless channels is considered. In particular, for independent identically distributedâ€¦ (More)

We determine the reliability function of the exponential-server timing channel (ESTC) in the limit as the data rate approaches zero. The limit shows that at low rates, the ESTC is strictly moreâ€¦ (More)

For a singular and symmetric discrete memoryless channel with positive dispersion, the third-order term in the normal approximation is shown to be upper bounded by a constant. This finding completesâ€¦ (More)

We study a hypothesis testing problem in which data are compressed distributively and sent to a detector that seeks to decide between two possible distributions for the data. The aim is toâ€¦ (More)

We describe a scheme for rate-distortion with distributed encoding in which the sources to be compressed contain a common component. We show that this scheme is optimal in some situations and that itâ€¦ (More)

We provide a refinement of the sphere-packing bound for constant composition codes over asymmetric discrete memoryless channels that improves the subexponential factor in front of the exponent. Theâ€¦ (More)
