Zusammenfassung: | FIELD: communication. SUBSTANCE: device has n arrays, each of which has heavy structure noise rejection unit 3, which first group of inputs is connected to outputs of reference signal conditioner 4; second group of inputs is connected to outputs of control unit 5. Output of rejection unit 3 is connected to first input of commutator 6, which second input is connected to input of rejection unit 3 and one of network outputs of interface 2. Third input of commutator 6 is connected to output of control unit 5. Output of commutator 6 is connected to input of receiver 1, which one output is connected to one of inputs of first group of inputs of control unit 5 for all arrays and to one of inputs of reference signal conditioners 4 for n-1 arrays. Second output of receiver 1 is connected through received signals level analyzer 7 to one input of second group of inputs of control unit 5 for all n arrays. This results in elimination of transmission of service information, decreased requirements for precision of power levels of antenna system, decreased number of power levels. EFFECT: increased stability to noise. 6 dwg1 |
