Variable-length codes independent or closed with respect to edit relations
AbstractWe investigate inference of variable-length codes in other domains of computer science, such as noisy information transmission or information retrieval-storage: in such topics, traditionally mostly constant-length codewords act. The ...

Noise enhancement and SNR equivalence in Bernoulli nonuniform sampling
CogART '11: Proceedings of the 4th International Conference on Cognitive Radio and Advanced Spectrum ManagementArticle No.: 14, Pages 1–5https://doi.org/10.1145/2093256.2093270This paper addresses the problem of nonuniform spectral analysis and spectrum sensing by means of Bernoulli sampling. The statistical treatment of sampling shows that nonuniformly sampling below the Nyquist rate produces in average the effects of noise ...
