Redundancy in block coded modulations for channel equalization based on spatial and temporal diversity
Vázquez Grau, Gregorio; Rey Micolau, Francesc; Lamarca Orozco, M. Meritxell (Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertLinear block codes in the complex field can be applied in spatial and/or temporal diversity receivers in order to develop high performance schemes for (almost-) blind equalization in mobile communications. The proposed ... -
Robust power allocation algorithms for MIMO OFDM systems with imperfect CSI
Rey Micolau, Francesc; Lamarca Orozco, M. Meritxell; Vázquez Grau, Gregorio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2005-03-31)
Article
Accés obertThis paper presents a Bayesian approach to the design of transmit prefiltering matrices in closed-loop schemes robust to channel estimation errors. The algorithms are derived for a multiple-input multiple-output (MIMO) ... -
Transform modulations for mobile communications
Lamarca Orozco, M. Meritxell; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 1997)
Text en actes de congrés
Accés obertA new modulation scheme called transform modulations is proposed which improves the system performance in frequency-flat fading mobile channels. They ameliorate the effect of the fadings over the transmitted signal by ...
