Matching filters (102-1 to 102-n) find correlation by using a received signal and extract channel estimated values for users (1 to n). Threshold value processing sections (103-1 to 103-n) perform threshold value processings of the estimated electric power determined on the basis of the channel estimated values. A JD section (104) performs matrix operation by using the channel estimated values subjected to the threshold value processings. A multiplying section (105) multiplies the result of the matrix operation by the received signal. An identifier (106) makes a hard judgment of the result of the multiplication.

Des filtres d'adaptation (102-1 à 102n) trouvent la corrélation en utilisant un signal reçu et les valeurs estimées d'un canal extrait pour les utilisateurs (1 à n). un canal extrait. Des sections de traitement (103-1 à 103n) traitent les valeurs seuil de la puissance électrique estimée déterminée en fonction des valeurs estimées des canaux. La section JD (104) effectue des opérations matricielles en fonction des susdites valeurs estimées des canaux. Une section de multiplication (105) multiplie le résultat des opérations matricielles par le signal reçu, puis un identificateur (106) prononce un jugement tranché sur le résultat de la multiplication.
