Abstract
In this paper, the analysis of the signal transmission with complex binary amplitude manipulation through a nonlinear frequency-selective amplifier is performed. It was obtained the expressions for the spectrum of the amplitude-manipulated signal. Formulas were proposed for the main harmonics of the output signal in the form of segments of Volterra functional series. A computer simulation of the input amplifier circuit of the receiver of the MOTOROLA GP300 radio station was carried out using numerical integration methods and Volterra functional series. The spectrum and time function of the output signal are obtained for various parameters of frequencies and amplitudes of the manipulated signal. The probability of error is estimated depending on the frequency of the envelope of the amplitude-manipulated signal. The gain factor is analyzed and the effect of the signal amplitude on the degree of distortion of information when passing through the amplifier is investigated.
