Abstract: A method of, and a receiver for, detecting the presence of digitally modulated data signals in which the receiver is periodically energised to detect the presence of the signals. The received signals/noise are converted using a quadrature frequency translation stage ( 16, 17, 18 ) into a complex signal which after differential decoding ( 28 ) contain n samples for each transmitted bit. A running sum of successive groups of m samples, where m<n, is obtained and an absolute value (Xi) of each group is derived. A weighting value (Wi) is selected by comparing each absolute value with predetermined statistics of expected values and the weighting value selected is multiplied by the associated absolute value to produce a product (S). The product is compared in a comparator ( 56 ) with a further threshold level ( 58 ) to derive an indication of the presence of data in the received signals. If the indication is negative the receiver is powered down to save power.
