Improved audio coding using a psychoacoustic model based on a cochlear filter bank
Perceptual audio coders use an estimated masked threshold for the determination of the maximum permissible just-inaudible noise level introduced by quantization. This estimate is d...

Tradeoffs between the excess-code-length exponent and the excess-distortion exponent in lossy source coding
Lossy compression of a discrete memoryless source (DMS) with respect to a single-letter distortion measure is considered. We study the best attainable tradeoff between the exponent...

Robust bandlimited watermarking with trellis coded modulation
Digital watermarking is equivalent to bandlimited, powerlimited digital communication. The power limit is due to the requirement of imperceptible watermarks, and has long been rec...

Globally Optimal Uneven Error-Protected Packetization of Scalable Code Streams
In this paper, we present a family of new algorithms for rate-fidelity optimal packetization of scalable source bit streams with uneven error protection. In the most general settin...
