Summary:A method for spectrum sensing is described comprising receiving a signal using a plurality of receive antennas; forming a set of received signals including the received signal of each antenna; determining a cyclic auto-correlation of the set of received signals; estimating, for each receive antenna, channel state information of the radio channel via which the receive antenna receives the signal based on the determined cyclic auto-correlation; performing maximum ratio combining of the received signal samples based on the estimated channel state information; determining a measure of the cyclostationarity of the received signal based on the result of the maximum ratio combining; and performing cyclostationarity detection spectrum sensing based on the determined measure of the cyclostationarity of the received signal. L'invention porte sur un procédé de détection de spectre, lequel procédé comprend la réception d'un signal à l'aide d'une pluralité d'antennes de réception, la formation d'un ensemble de signaux reçus comprenant le signal reçu de chaque antenne, la détermination d'une auto-corrélation cyclique de l'ensemble de signaux reçus, l'estimation pour chaque antenne de réception des informations d'état de canal du canal radio par l'intermédiaire duquel l'antenne de réception reçoit le signal sur la base de l'auto-corrélation cyclique déterminée, la réalisation d'une combinaison à rapport maximal des échantillons de signaux reçus sur la base des informations d'état estimé de canal, la détermination d'une mesure de cyclo-stationnarité du signal reçu sur la base du résultat de la combinaison à rapport maximal, et la réalisation d'une détection de spectre de détection de cyclo-stationnarité sur la base d'une mesure déterminée de cyclo-stationnarité du signal reçu.
