New diversity combination algorithms for DVB-T COFDM mobile reception

New combination methods for the reception of DVB-T 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 CSI
_l,k
. Finally, better results are obtained compared to MRC algorithm with an adaptive algorithm using these new combination techniques using CSI
_l,k
criterion.
