Cramer-rao bound for time-delay estimation in the frequency domain
Serra, Jordi; Blanco, Luis; Nájar Martón, Montserrat (European Association for Signal Processing (EURASIP), 2009)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper a measure of performance of time delay estimators arising from a frequency model of the received signal is presented. The aim is to derive theoretical analysis of the Cramer-Rao bound (CRB) for time delay ... -
Hybrid analog-digital transmit beamforming for spectrum sharing satellite-terrestrial systems
Vazquez, Miguel Angel; Blanco, Luis; Artiga Campos, Xavier; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper deals with the problem of hybrid analog-digital transmit beamforming under spectrum sharing constraints. Hybrid multiantenna architectures are ideal for high throughput wireless links, where full-digital solutions ... -
Interference management in LTE-based HetNets: a practical approach
Font Bach, Oriol; Bartzoudis, Nikolaos; Pascual Iserte, Antonio; Payaró Llisterri, Miquel; Blanco, Luis; López Bueno, David; Molina Pena, Marc (Wiley-Blackwell, 2015)
Article
Accés obertInterference is a major obstacle in radio communications, especially when opportunistic frequency reuse is an inherent requirement for maximising spectral ef¿ciency in heterogeneous networks. A typical example is encountered ... -
Multiuser downlink hybrid analog-digital beamforming with individual SINR constraints
Vazquez, Miguel Angel; Blanco, Luis; Pérez Neira, Ana Isabel (VDE-Verlag, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper deals with the problem of multiuser transmit hybrid analog-digital beamforming. Precisely, we tackle the problem of transmit power minimization under minimum signal-to-noise-plus-interference ratio (SINR) ... -
Non-convex consensus ADMM for satellite precoder design
Vazquez, Miguel Angel; Konar, Aritra; Blanco, Luis; Sidiropoulos, Nicholas D.; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés restringit per política de l'editorialOwing to the rapidly increasing traffic demands on satellite connectivity, the current exclusive frequency allocation is becoming obsolete. Instead, aggressive frequency reuse and interference mitigation techniques are ... -
Phase only transmit beamforming for spectrum sharing microwave systems
Vázquez, Miguel Ángel; Blanco, Luis; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés obertThis paper deals with the problem of phase-only transmit beamforming in spectrum sharing microwave systems. In contrast to sub-6 GHz schemes, general microwave systems require a large number of antennas due to its huge ... -
Relay subset selection in cognitive networks with imperfect CSI and individual power constraints
Nájar Martón, Montserrat; Blanco, Luis (Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés obertThis paper considers the relay subset selection problem in an underlay cognitive network in which two secondary users communicate assisted by a set of N potential relays. More specifically, this paper deals with the joint ... -
Sparse beamforming for mmWave spectrum sharing systems
Vázquez Oliver, Miguel Ángel; Blanco, Luis; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper deals with the problem of sparse beamforming for interference mitigation in milimiter wave (mm Wave) frequency bands. Multiantenna solutions in mmWave are generally implemented with phase shifters which are known ... -
Sparse multiple relay selection for network beamforming with individual power constraints using semidefinite relaxation
Blanco, Luis; Nájar Martón, Montserrat (2016-02)
Article
Accés obertThis paper deals with the multiple relay selection problem in two-hop wireless cooperative networks with individual power constraints at the relays. In particular, it addresses the problem of selecting the best subset of ... -
Subset relay selection in wireless cooperative networks using sparsity-inducing norms
Blanco, Luis; Nájar Martón, Montserrat (2014)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper addresses the problem of multiple relay selection in a two-hop wireless cooperative network. In particular, the proposed technique selects the best subset of relays, in a distributed beamforming scheme, which ...
