Abstract

PURPOSE:To make the amplitude of each burst of an input signal constant in the demodulator in a TDMA digital link of satellite communication. CONSTITUTION:An input from a terminal 1 is applied to a peak detector 3 through a voltage control attenuator 2, detects a peak value of the whole bursts, is compared with a reference voltage 4, amplified 6, after filtered 7 on its wave, enters into a attenuator 2, and when the peak value of the input is larger than the reference value, it organizes a loop to implement attenuation and control of it. Further, since there are a large and small difference among each burst, these signals are amplified 9, sent to a voltage control variable attenuator 12, and the output is detected 10 on its burst amplitude, compared with the reference voltage by a digital comparator 11, with a controller 13 stored the difference from the reference voltage of each burst in before 1 frame, defines control volume of the next following frame, with which stablization of amplitude control and unification of the amplitude of each burst are implemented.
