Title: New Diversity Combination Algorithms for DVB-T COFDM Mobile Reception
Author(s): Christian Brousseau   Franck Nivole   Stéphane Avrillon   Louis Bertel   

Abstract: New combination methods for the reception of DVB-T (Digital Video Broadcasting on Terrestrial networks) signals in mobile receiver configuration are proposed. These methods are tested for different real reception problem cases. The experimental mobile system is presented, including demodulation tools, and several new combination techniques. These techniques are based on MRC algorithm improving by an original criterion, called CSIl,k. Finally, better results are obtained, compared to MRC algorithm, with an adaptive algorithm using these new combination techniques based on CSIl,k criterion.

Keywords: DVB-T, mobile communication, diversity systems, signal processing, broadcast receivers, radio propagation.
