A refinement of expurgation
(Institute of Electrical and Electronics Engineers (IEEE), 2024-12)
Article
Open AccessWe 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 small fraction of codewords from a randomly ... -
A vulnerability factor for ECC-protected memory
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessFault injection studies and vulnerability analyses have been used to estimate the reliability of data structures in memory. We survey these metrics and look at their adequacy to describe the data stored in ECC-protected ... -
Analysis the use of large language model for automated program repair
(Universitat Politècnica de Catalunya, 2023-06-29)
Bachelor thesis
Restricted access - confidentiality agreementAutomated program repair (APR) is a research field that develops multiple techniques to fix software bugs automatically. For a long time, the proposed solutions were based on heuristics and patterns, but since the appearance ... -
Asymptotic MAP upper bounds for LDPC codes
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessThis paper aims at computing tight upper bounds for the maximum a posteriori threshold of low-density parity check codes in the asymptotic blocklength regime for the transmission over binary-input memoryless symmetricoutput ... -

Evaluating built-in ECC of FPGA on-chip memories for the mitigation of undervolting faults
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessVoltage underscaling below the nominal level is an effective solution for improving energy efficiency in digital circuits, e.g., Field Programmable Gate Arrays (FPGAs). However, further undervolting below a safe voltage ... -
Exploiting asynchrony from exact forward recovery for DUE in iterative solvers
(Association for Computing Machinery (ACM), 2015)
Conference report
Open AccessThis paper presents a method to protect iterative solvers from Detected and Uncorrected Errors (DUE) relying on error detection techniques already available in commodity hardware. Detection operates at the memory page ... -

Étude d’un émetteur-récepteur faster-than-Nyquist de faible complexité pour les communications par satellite
(Universitat Politècnica de Catalunya, 2015-10-01)
Master thesis (pre-Bologna period)
Open Access
Covenantee: Institut Supérieur de l'Aéronautique et de l'EspaceCapacity increase in satelite communications systems is nowadays a main concern. In order to increase the spectral efficiency of such systems, a research topic consists in specifying non-orthogonal modulations called ... -
Generalized perfect codes for symmetric classical-quantum channels
(Institute of Electrical and Electronics Engineers (IEEE), 2022-09)
Article
Open AccessWe define a new family of codes for symmetric classical-quantum channels and establish their optimality. To this end, we extend the classical notion of generalized perfect and quasi-perfect codes to channels defined over ... -

Article
Open AccessIn this paper, we present a study on the performance of direct-oversampling correlator-type receivers in chaos-based direct-sequence code division multiple access systems over frequency non-selective fading channels. At ... -
State estimation and decoupling of unknown inputs in uncertain LPV systems using interval observers
(2017-06-13)
Article
Open AccessThis paper proposes a linear parameter varying (LPV) interval observer for state estimation and unknown inputs decoupling in uncertain continuous-time LPV systems. Two different problems are considered and solved: (1) the ... -
