A Refinement of Expurgation
Giuseppe Cocco, Albert Guillén i Fàbregas, Josep Font-Segura
We show that for a wide range of channels and code ensembles with pairwise-independent codewords, with probability tending to 1 with the code length, expurgating an arbitrarily sma…
Typical Error Exponents: A Dual Domain Derivation
Giuseppe Cocco, Albert Guillén i Fàbregas, Josep Font-Segura
This paper shows that the probability that the error exponent of a given code randomly generated from a pairwise independent ensemble being smaller than a lower bound on the typica…
Concentration Properties of Random Codes
Lan V. Truong, Giuseppe Cocco, Josep Font-Segura +1
This paper studies the concentration properties of random codes. Specifically, we show that, for discrete memoryless channels, the error exponent of a randomly generated code with…
Caching in Heterogeneous Networks with Per-File Rate Constraints
Estefanía Recayte, Giuseppe Cocco
We study the problem of caching optimization in heterogeneous networks with mutual interference and per-file rate constraints from an energy efficiency perspective. A setup is cons…
The Sum-Rate-Distortion Region of Correlated Gauss-Markov Sources
Giuseppe Cocco, Laura Toni
Efficient low-delay video encoders are of fundamental importance to provide timely feedback in remotely controlled platforms such as drones. In order to fully understand the theore…
