METHOD FOR ADDING SIGNALS FROM SPACED ANTENNAS Russian patent published in 1999 - IPC

FIELD: digital data transmission. SUBSTANCE: in adding signals arriving from spaced antennas, readings taken off outputs of matched demodulator filters of each antenna are summed up once within data signal length; readings are submitted in digital form. Adding points provide for time coincidence of data streams coming from each antenna. Method provides for using antennas spaced thousands of kilometers apart which is most essential to ensure communication with space vehicles in deep space. EFFECT: reduced requirements to accuracy of time coincidence of received signals and to linearity of communication line. 2 dwg
