<p>Communication receiving unit for the suppression of noise and jamming signals which receiving unit comprises: - a plurality of antenna elements (1A-1N); - adaptive weighting filters (7A, a,..., 7N, k+1) connected thereto; - a combination circuit (4) connected to said filters (7A,a,..., 7N k+1); - a detector (5) connected to the combination circuit (4) suited to generate a replica (d) of the information-supplying carrier signal for demodulating the signal (y) of the combination circuit (4) to the information-related frequency band; and - means (8) for adjusting said filters (7A, a,..., 7N, k+1). The detector (5) comprises first means (40, 41) for determining a time-averaged power value (W1) concerning the signal (y) from the combination circuit (4) and second means (42, 43) for determining a time-averaged value (W2) of the cross-correlation concerning the output signal (y) and the replica (d). The adjusting means (8) are designed for generating modified adjusting signals on the basis of the supplied time-averaged values (W1 and W2) for a more accurate adjustment of the weighting filters (7A,a,..., 7N,k+1).</p> |
