Additive MDS Codes
(Universitat Politècnica de Catalunya, 2020-10)
Master thesis
Restricted access - author's decisionIn this master thesis, we present examples of additive nonlinear MDS codes over nonprime fields. Moreover, we prove the MDS conjecture for additive nonlinear codes for the alphabets F9 and F16, preserving linearity over ... -
Array codes and graph decompositions
(Universitat Politècnica de Catalunya, 2019-01)
Bachelor thesis
Open AccessArray codes are intended to correct bursts of errors in communication through noisy channels. As in regular codes there is a notion of maximum distance separating (MDS) array codes. A so-called Perfect One-Factorization ... -
Construcció de codis correctors a partir de configuracions i grafs
(Universitat Politècnica de Barcelona. Centre de Càlcul, 1986-06)
Article
Open AccessSe trata de presentar algunas de las relaciones de carácter básicamente combinatorio que es posible encontrar entre dos tipos importantes de estructuras de incidencia, como son los grafos simétricos y las t-configuraciones, ... -
Códigos convolucionales de Goppa
(2008-04-03)
Audiovisual
Open AccessSe hará una introducción a la teoría de códigos convolucionales y a continuación describiremos la construcción de códigos convolucionales como códigos de valoración en una familia uniparamétrica de curvas algebraicas. Los ... -
Development and evaluation in AVInspector
(Universitat Politècnica de Catalunya, 2011-12-20)
Bachelor thesis
Restricted access - author's decisionAVInspector is a software developed at Fraunhofer IDMT that allows analysis and detection of audio and video errors. The software consists of several independent modules for every kind of error and a GUI which manages the ... -

Feasibility and implementation study of a high-throughput DVB-S2 LDPC Decoder on FPGA architecture
(Universitat Politècnica de Catalunya, 2014-10-16)
Master thesis
Restricted access - author's decision[ENGLISH] The aim of this project consists in the study of the error correcting codes LDPC (Low Density Parity Check) in the context of the DVB-S2 standard (Digital Video Broadcasting for Satellite version 2) in order to ... -
Goal-oriented h-adaptivity for the Helmholtz equation: error estimates, local indicators and refinement strategies
(2011-01-14)
Article
Open AccessThis paper introduces a new goal-oriented adaptive technique based on a simple and effective post-process of the finite element approximations. The goal-oriented character of the estimate is achieved by analyzing both the ... -

Master thesis (pre-Bologna period)
Open AccessBCJR algorithm implementation written in Java. Obtention of the probability expressions and error correction. Capability of identifying conspiring users within dual binary Hamming codes. GUI implementation. -
Locating-dominating codes: Bounds and extremal cardinalities
(2013-09-01)
Article
Restricted access - publisher's policyIn this work, two types of codes such that they both dominate and locate the vertices of a graph are studied. Those codes might be sets of detectors in a network or processors controlling a system whose set of responses ... -
Maximum distance separable codes
(Universitat Politècnica de Catalunya, 2014-10)
Bachelor thesis
Open AccessThe focus of this bachelor thesis are maximum distance separable codes. A code is used to communicate over noise channel so any interferences that may occur can be detected and corrected. Maximum distance separable codes ... -
MDS array codes and perfect factorizations of graphs
(Universitat Politècnica de Catalunya, 2020-07)
Master thesis
Restricted access - author's decisionArray Codes form a class of Error Correcting Codes which are specifically designed to deal with natural types of errors in communication devices which appear in clusters as opposite to randomly scattered within the string ... -
Optimization of Random Linear Network Coding protocols for multipath communications in heterogeneous networks
(Universitat Politècnica de Catalunya, 2019-04-25)
Bachelor thesis
Open Access
Covenantee: Technische Universität DresdenIn the next upcoming mobile generation era (5G), the demands for high-data-rate transmissions is predicted to grow considerably. Among new studies focused on how to support such demands, Random Linear Network Coding (RLNC) ... -
Parallelization of the interpolation process in the Koetter-Vardy soft-decision list decoding algorithm
(2012)
Conference lecture
Open AccessList decoding is a decoding strategy that provides a set of codewords at the output of the channel decoder. Since this technique corrects errors beyond the correcting bound of the code, upper layers in the application or ... -

(Universitat Politècnica de Barcelona. Centre de Càlcul, 1988)
Article
Open AccessUno de los aspectos claves en las telecomunicaciones está relacionado con el uso de los códigos correctores de errores para la transmisión de información. Actualmente se utiliza una clase muy simple de códigos; la ... -
Use of Turbo Codes with Low-Rate Convolutional Constituent Codes in Fingerprinting Scenarios
(IEEE, 2011)
Conference lecture
Restricted access - publisher's policyWe discuss the use of turbo codes in fingerprinting schemes. More precisely, we present a family of turbo codes that are secure against attacking coalitions of size 2. This family is build upon a class of low-rate convolutional ...
