Low-Complexity Near-Optimal Decoding for Analog Joint Source Channel Coding Using Space-Filling Curves
Fresnedo, Óscar; Vázquez-Araújo, Francisco J.; Castedo, Luis; Garcia-Frias, Javier (Institute of Electrical and Electronics Engineers, 2013-04)[Abstract]: Analog Joint Source-Channel Coding (JSCC) is a communication strategy that does not follow the separation principle of conventional digital systems but approaches the optimal distortion-cost tradeoff over AWGN ... -
PICTOTEMPO: An App for Personal Organization in Autism Spectrum Disorders
Vila-Muñoz, Noé; Castro-Castro, Paula-María; Fresnedo, Óscar (MDPI, 2021)[Abstract] In this work, we develop a mobile application which allows to create digital schedules for children with autism spectrum disorder. These schedules comprise a sorted sequence of tasks or activities which facilitates ... -
Rank Constrained Precoding for the Downlink of mmWave Massive MIMO Hybrid Systems
González-Coma, José P.; Fresnedo, Óscar; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2021-02-11)[Abstract] The hybrid design of precoding schemes for millimeter-wave communications allows exploiting the gains by using large antenna array with an affordable hardware cost and power consumption. In this work, we present ... -
Service-Learning methodology to develop Bachelor’s Thesis in Information and Computer Science Degrees
Castro-Castro, Paula-María; Fresnedo, Óscar; Dapena, Adriana; Pereira-Loureiro, Javier; Vázquez Araújo, Francisco Javier (PKP Publishing Services Network, 2024)[Abstract]: Service-Learning (SL) is a powerful methodology to acquire competences and values in Higher Education.

Transmission of Analog Information Over the Multiple Access Relay Channel Using Zero-Delay Non-Linear Mappings
Fresnedo, Óscar; Suárez-Casal, Pedro; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2019-04-04)[Abstract]: We consider the zero-delay encoding of discrete-time analog information over the Multiple Access Relay Channel (MARC) using non-linear mapping functions. On the one hand, zero-delay non-linear mappings are ... -
