Optimal MISO pre-equalization for filter bank multicarrier systems
Caus López, Marius; Pérez Neira, Ana Isabel (2009)
Text en actes de congrés
Accés restringit per política de l'editorialOne of the phenomena that degrades the performance of multicarrier modulation (MCM) systems is the spectral nulls that multipath channel may have. As a result, the affected subcarrier signals may be severely degraded ... -
SDMA for filterbank with Tomlinson Harashima precoding
Caus López, Marius; Pérez Neira, Ana Isabel (2013)
Text en actes de congrés
Accés restringit per política de l'editorialSeveral studies have revealed that OFDM is outperformed in several areas by the filter bank based multicarrier (FBMC) modulation thanks to pulse shaping techniques. Nevertheless, the combination of FBMC with multi-antenna ... -
Space-Time Receiver for Filterbank Based Multicarrier Systems
Caus López, Marius; Pérez Neira, Ana Isabel (2011)
Text en actes de congrés
Accés restringit per política de l'editorialBy including a cyclic prefix (CP), systems based on orthogonal frequency division multiplexing (OFDM) are capable of mitigating multipath with a single tap equalizer. Aiming at increasing the spectral efficiency, filter ... -
Subcarrier allocation and power loading strategies for multi-user broadcast FBMC/OQAM systems
Caus López, Marius; Pérez Neira, Ana Isabel (Institute of Electrical and Electronics Engineers (IEEE), 2012)
Comunicació de congrés
Accés restringit per política de l'editorialWith the objective of maximizing the sum-rate this paper tackles the subcarrier and the power allocation problems in the context of multi-user FBMC. Under highly frequency selective channels the demodulated data is ... -
Transmit and receive filters for MISO FBMC systems subjected to power constraints
Caus López, Marius; Pérez Neira, Ana Isabel (2011)
Text en actes de congrés
Accés restringit per política de l'editorialBuild upon the OFDM/OQAM scheme this paper addresses the design of linear transmit and receive filters. Aiming at enhancing the robustness against multipath fading, two novel techniques are proposed. The first one jointly ...
