Adaptive control of the signal at the output of adaptive antenna in digital channel of troposphere communication The paper examines the solution of scientific problem on determining the information reliability of digitalchannel of troposphere communication with an adaptive antenna, when signals at the output of the adaptive antenna and adaptive receiver are controlled simultaneously and compared with the fixation of the conditions of existence of informational redundancy of the channel, that automatically specifies the standard information reliability of the digital channel at an troposphere communication station.
