description A method of determining as to whether a received signal includes an information signal is provided. The method provided includes determining a covariance matrix from a received signal and transforming the covariance matrix into a transformed covariance matrix, wherein the transformation is configured such that the transformed covariance matrix is a non-diagonal matrix in case the received signal includes the information signal, wherein the non-diagonal matrix includes non-zero non-diagonal matrix elements. The method provided further includes determining a first function using at least one of the non-zero non-diagonal matrix elements of the transformed covariance matrix, determining a second function using at least one matrix element of the transformed covariance matrix, wherein the second function is different from the first function, and determining as to whether a received signal includes an information signal based on a comparison of a value of the first function and a value of the second function. L'invention concerne un procédé de détermination de savoir un signal reçu comprend ou non un signal d'informations. Le procédé comprend la détermination d'une matrice de covariance à partir d'un signal reçu et la transformation de la matrice de covariance en une matrice de covariance transformée, la transformation étant configurée de telle sorte que la matrice de covariance transformée est une matrice non diagonale dans le cas où le signal reçu comprend le signal d'informations, la matrice non diagonale comprenant des éléments de matrice non diagonaux non nuls. Le procédé comprend en outre la détermination d'une première fonction à l'aide d'au moins l'un des éléments de matrice non diagonaux non nuls de la matrice de covariance transformée, la détermination d'une seconde fonction à l'aide d'au moins un élément de matrice de la matrice de covariance transformée, la seconde fonction étant différente de la première fonction, et la détermination de savoir si un signal reçu comprend ou non un signal d'informations sur la base d'une comparaison d'une valeur de la première fonction et d'une valeur de la seconde fonction.
