Irregular variable length coding

FACULTY OF ENGINEERING, SCIENCE AND MATHEMATICS SCHOOL OF ELECTRONICS AND COMPUTER SCIENCE Doctor of Philosophy Irregular Variable Length Coding by Robert G. Maunder In this thesis, we introduce Irregular Variable Length Coding (IrVLC) and investigate its applications, characteristics and performance in the context of digital multimedia broadcast telecommunications. During IrVLC encoding, the m...

Near-Capacity Variable Length Coding

Quantum universal variable-length source coding

We construct an optimal quantum universal variable-length code that achieves the admissible minimum rate, i.e., our code is used for any probability distribution of quantum states. Its probability of exceeding the admissible minimum rate exponentially goes to 0. Our code is optimal in the sense of its exponent. In addition, its average error asymptotically tends to 0.

Alternating coding for universal variable length code

decoding ability as well as immediate error detection and (vLc) is used in a large variety of location ability without performing decoding bi-directionlossless compression applications. A specially designed ally. This improves the decoding throl"&Put without the VLC, called "Universal Variable Length Code" (UVLC), expense of dual decoder structures. The ALT coded UVLC is utilized in the latest ...

Variable-length channel coding with noisy feedback

It is known that perfect noiseless feedback can be used to improve the reliability of communication systems. We show how to make those gains robust to noise on the feedback link. We focus on feedback links that are themselves discrete memoryless channels. We demonstrate that Forney’s erasure-decoding exponent is achievable given any positive-capacity feedback channel. We also demonstrate that a...
