Efficient loopless generation of Gray codes for k-ary trees
Vajnovszki recently developed a loopless algorithm [Inform. Process. Lett. 68 (1998) 113] to enumerate Gray codes for binary trees, and then Korsh and Lafollette gave a loopless a...

Exploiting UEP in QAM-based BICM: interleaver and code design
In this paper we formally analyze the interleaver and code design for QAM-based BICM transmissions using the binary reflected Gray code. We develop analytical bounds on the bit e...

A universal scheme for Wyner-Ziv coding of discrete sources
We consider the Wyner-Ziv (WZ) problem of lossy compression where the decompressor observes a noisy version of the source, whose statistics are unknown. A new family of WZ coding a...

DHV: A Code Consistency Maintenance Protocol for Multi-hop Wireless Sensor Networks
Ensuring that every sensor node has the same code version is challenging in dynamic, unreliable multi-hop sensor networks. When nodes have different code versions, the network may...

Limits to List Decoding Random Codes
It has been known since [Zyablov and Pinsker 1982] that a random q-ary code of rate 1 − Hq(ρ) − ε (where 0 < ρ < 1 − 1/q, ε > 0 and Hq(·) is the q-ary entropy ...
