CA 2328171

A dual-mode receiver is provided to receive QPSK- modulated satellite signals and multicarrier modulated (MCM) terrestrial signals. The dual-mode receiver has a combined architecture comprising a minimal number of filters selected to facilitate both QPSK and MCM demodulation.

L'invention concerne un récepteur à double mode permettant de recevoir des signaux transmis par satellites, à modulation par déplacement de phases en quadrature, et des signaux de terre modulés à porteuses multiples. Ce récepteur à double mode présente une architecture combinée comportant un nombre minimal de filtres sélectionnés pour faciliter la démodulation tant par déplacement de phases en quadrature que par modulation à porteuses multiples.
