Abstract
PURPOSE:To eliminate the waveform distortion of a nonlinear transmission line, by adding an equalizer which estimates the output signal of a nonlinear circuit. CONSTITUTION:The output of a microwave receiving selecting filter has the waveform distortion equalized by the first equalizer 40. The output of the first equalizer 40 is given to a nonlinear correcting circuit 41 having a characteristic opposite to a characteristic f(x) of a nonlinear circuit. The output of the nonlinear correcting circuit 41 is given to the second equalizer 42 which equalizes the waveform distortion of the band limiting filter of the transmission side, and the transmission code transmitted from the transmission side is obtained from an output terminal 142. The first equalizer 40 estimates a signal of the input terminal of the receiving selecting filter with precision corresponding to the magnitude of a receiving input noise to eliminate the distortion of the digital signal which passes through the nonlinear transmission line.
