Blind equalization based on spatial and temporal diversity in block coded modulations
(Institute of Electrical and Electronics Engineers (IEEE), 1998)
Text en actes de congrés
Accés obertLinear block codes can be applied in spatial and/or temporal diversity receivers in order to develop high performance schemes for blind equalization in mobile communications. The proposed technique uses the structure of ... -
Blind equalization of DS-CDMA and MC-CDMA modulations in time-variant frequency selective channels
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertThe paper addresses the blind equalization problem of spread spectrum modulations in the presence of fast time-variant frequency-selective channels. The basic assumption of the paper is that the channel response exhibits ... -
Búsqueda de la calidad en acción humanitaria. El papel de la tecnología.
(2007-06-29)
Article
Accés obertEl sector humanitario, sobre todo en la vertiente de emergencias, se mueve entre la apariencia de ser el que más ha incorporado el uso de tecnologías en el ámbito de la cooperación, y la realidad más habitual de moverse ... -
Channel-aware energy allocation for throughput maximization in massive low-rate multiple access
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Text en actes de congrés
Accés obertA multiple access (MA) optimization technique for massive low-rate direct-sequence spread spectrum communications is analyzed in this work. A dense network of users transmitting at the same rate to a common central node ... -
Correlation study between the access mark and the performance in project-based and standard courses
(Universitat Politècnica de Catalunya, 2022-09)
Text en actes de congrés
Accés obertThe access mark to engineering studies is often used as an a priori success estimator. In our institution, we have observed that the correlation of the access mark with the grades obtained in project-based courses (R=0.52) ... -
Correlation study between the performance in different engineering courses and project-based courses
(NTNU SEED, 2023)
Comunicació de congrés
Accés obertIn a previous study, already published (Bragós, 2022), we analyzed the correlation between the University access mark to the engineering studies with the grades obtained in projectbased courses and in non-project-based ... -

DA-GLRT burst detection and synchronization based on a chirp-like preamble
(2008)
Text en actes de congrés
Accés restringit per política de l'editorialA specific preamble for the tasks of signal detection and synchronization in burst digital communications is presented. The preamble resembles a chirp signal used in RADAR applications. Its main benefit is that it allows ... -
Decentralized random energy allocation for massive non-orthogonal code-division multiple access
(2019-10-07)
Article
Accés obertThis work studies the spectral efficiency achievable when a very large number of terminals are connected simultaneously to a central node (uplink) through independent and identically-distributed flat-fading channels. ... -
Diversity in mobile communications for blind detection of block-coded modulations
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertSpatial, temporal, and frequency diversity structures are analyzed to address the blind equalization problem in the presence of time-variant frequency selective channels. The aim of the paper is to present equalization ... -
Energy and rate allocation for massive multiple access with interference cancelation
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Article
Accés obertThis article addresses the problem of energy and code allocation to many users accessing, under spreading-based nonorthogonal multiple access, a wireless node set up with a successive interference cancellation architecture ... -
