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)
Open AccessLinear 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 ...

Open AccessA 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 ...
