Carrier Frequency Offset Compensation for OFDMA Systems Using Circular Banded Matrices
(Planta Piloto de Ingeniería Química, 2013-07)
Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality ...
Design of an optical beam combiner for dual band observation with ALMA
(IEEE, 2017)
The aim of this work is to improve high-frequency calibration data on long baseline observations for the ALMA antennas. A dual-frequency atmospheric phase error calibration method is ...

A Cognitive Way to Access the Frequency Spectrum
(2013-07-05)
Cognitive radio (CR) is an emergent technology in wireless communication. It aims at improve considerably spectrum use by allowing dynamic spectrum access (DSA). The DSA can be performed in different ways, e.g. interweave ...
Millimeterwave channel characterization for wehicular communications
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2022-12)
The increasing demand for more sensors inside vehicles pursues the intention of making
vehicles more “intelligent”. This vision of fully connected, all-sensed, and autonomous
cars are becoming more tangible and will ...
