  • Communication receiving unit for the suppression of noise and interference signals
    Patent number: 4608701
    Abstract: A 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 (7.sub.A,a, . . . , 7.sub.N,k+1) connected thereto;a combination circuit (4) connected to the weighting filters (7.sub.A,a, . . . , 7.sub.N,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; anda unit (8) for adjusting the weighting filters (7.sub.A,a, . . . , 7.sub.N,k+1).The detector (5) comprises a circuit (40, 41) for determining a time-averaged power value (W.sub.1) concerning the signal (y) from the combination circuit (4), and a circuit (42, 43) for determining a time-averaged value (W.sub.2) of the cross-correlation concerning the output signal (y) and the replica (d).
