A Test Vector Generation Method Based on Symbol Error Probabilities for Low-Complexity Chase Soft-Decision Reed-Solomon Decoding

Valls Coquillat, Javier; Torres Carot, Vicente; Canet Subiela, Mª José; García-Herrero, Francisco M. (Institute of Electrical and Electronics Engineers, 2019-06)

[EN] This paper presents a low-complexity chase (LCC) decoder for Reed-Solomon (RS) codes, which uses a novel method for the selection of test vectors that is based on the analysis of the symbol error probabilities derived ...
Automatic extraction of shorelines from Landsat TM and ETM+ multi-temporal images with subpixel precision

Pardo Pascual, Josep Eliseu; Almonacid Caballer, Jaime; Ruiz Fernández, Luis Ángel; Palomar-Vázquez, Jesús (Elsevier, 2012-08)

A high precision geometric method for automated shoreline detection from Landsat TM and ETM+ imagery is presented. The methodology is based on the application of an algorithm that ensures accurate image geometric registration ...
Decodificador de códigos LDPC no binarios basado en el algoritmo T-EMS

Lacruz Jucht, Jesús Omar (Universitat Politècnica de València, 2014-11-24)

[EN] In this work a non-binary LDPC decoder based on T-EMS algorithm is proposed. A full parallel architecture of the check node has been implemented and a layered schedule is used for the decoder. The proposed decoder has ...
Detection and correction of linguistic errors: results according to linguistic preferences and uses

Cicres Bosch, Jordi; Llach, Silvia; de-Ribot, María Dolors (Editorial Universitat Politècnica de València, 2014-07-01)

[EN] This paper examines the ability of 256 university students to detect and correct errors related to different linguistic aspects of Catalan, by means of a test including correct and incorrect sentences. The sentences ...
Fading Margin Reduction due to Inter-Burst Upper Layer FEC in Terrestrial Mobile Broadcast Systems

Gómez Barquero, David; Gozálvez Serrano, David; Gómez Molina, Pedro Fernando; Cardona Marcet, Narciso (Institute of Electrical and Electronics Engineers (IEEE), 2011-09)

In this paper, we investigate the reduction of the shadowing fading margin that can be achieved with interburst upper layer forward error correction (UL-FEC) in terrestrial mobile broadcast systems with time slicing (i.e., ...
Layer-Aware Forward Error Correction for Mobile Broadcast of Layered Media

Hellge, Cornelius; Gómez Barquero, David; Schierl, Thomas; Wiegand, Thomas (Institute of Electrical and Electronics Engineers (IEEE), 2011-06)

The bitstream structure of layered media formats such as scalable video coding (SVC) or multiview video coding (MVC) opens up new opportunities for their distribution in Mobile TV services. Features like graceful degradation ...
Serial symbol-reliability based algorithm for decoding non-binary LDPC codes

García Herrero, Francisco Miguel; Canet Subiela, Mª José; Valls Coquillat, Javier; Flanagan, Mark F. (Institute of Electrical and Electronics Engineers (IEEE), 2012-06)

A symbol-reliability based decoding algorithm with serial schedule for non-binary low-density parity-check (LDPC) codes is presented. Performance results, together with implementation complexity analysis, are provided for ...
Syndrome-Based Min-Sum vs OSD-0 Decoders: FPGA Implementation and Analysis for Quantum LDPC Codes

Valls Coquillat, Javier; García-Herrero, Francisco; Raveendran, Nithin; Vasic, Bane (Institute of Electrical and Electronics Engineers, 2021)

[EN] Quantum processors need to improve their reliability to scale up the number of qubits and increase the number of algorithms that can execute. To reduce the logical error rate of the quantum systems, the use of error ...
