A reception device, which communicates with a transmission device having multiple transmission antennas, includes: at least one reception antenna which receives multiple transmission signals that are transmitted from the multiple transmission antennas by the transmission device; a Fourier transform unit which transforms the signals received by the reception antenna from a time domain into a frequency domain; a propagation channel estimating unit which calculates propagation channel estimation values by estimating propagation channels between the multiple transmission antennas and the reception antenna; and a signal detecting unit which detects the multiple transmission signals by dividing multipaths from the signals that are transformed into the frequency domain by the Fourier transform unit.

L'invention concerne un appareil récepteur qui communique avec un appareil émetteur équipé d'une pluralité d'antennes d'émission. L'appareil récepteur comporte les éléments suivants : au moins une antenne de réception qui reçoit une pluralité de signaux émis par les antennes d'émission; une partie transformée de Fourier qui applique aux signaux reçus par l'antenne de réception un traitement qui transforme le domaine temporel en domaine fréquentiel; une partie estimation du trajet de propagation qui estime un trajet de propagation entre les antennes d'émission et l'antenne de réception et calcule une valeur estimée du trajet de propagation; et une partie détection de signal qui sépare les trajets multiples des signaux qui ont été transformés vers le domaine fréquentiel par la partie transformée de Fourier et détecte une pluralité de signaux émis.
