Abstract
FIELD: radio communications; satellite communication systems.SUBSTANCE: proposed adaptive system has on sending end series-connected carrier generator, broadband signal shaper, and 90 deg. phase shifter whose second input is connected to output of auxiliary-sequence generator; input of the latter is connected to second output of broadband signal shaper. Binary-data source output is connected to second input of broadband signal shaper. Connected to outputs of 90 deg. phase shifter are integrated inputs of N band filters which are series-connected to N switches, adder, and AGC power amplifier. In addition, on sending end it has noise situation analyzer provided with separate antenna; its outputs are integrated with second inputs of respective switches. On receiving end it has series-connected 90 deg. phase shifter, data synchronizing and allocating unit, and auxiliary-sequence generator whose output is connected to one input of 90 deg. phase shifter. On receiving end it also has series-connected pre-selection unit, N integrated-input band filters, N switches, and adder; output of the latter is connected to other input of 90 deg. phase shifter; it also has decision unit whose inputs and outputs are connected to respective outputs of N band filters and to second inputs of switches.EFFECT: enhanced immunity of communication system to noise including bunched-spectrum noise.1 cl, 3 dwg
