Abstract The invention concerns a method of estimating the noise power of a given digital signal (cell1) assigned a code, this signal being received by a receiver (56) simultaneously with a plurality of other digital signals assigned different codes.The noise powers are estimated for each of the received digital signals (cell1, cell2, . . . cellM') assigned codes and there is assigned, to the given signal, the mean noise power (62) which is the ratio between, on the one hand, the sum of the estimated noise powers and, on the other hand, the total number M of received codes.
