To software implementation of Sharapov's analytical method for estimating the parameters of a frequency mixture without combination frequencies and solving optimization problem

Abstract

The paper presents key aspects that allow for the first time to algorithmize Sharapov's analytical method for evaluating the parameters of transformation zones taking into account the combinational interfering frequencies at the mixer output under the condition of transposition of the input signal spectrum. As a frequency conversion, the case is considered when the local oscillator frequency is less than the signal frequency. The possibility of calculating the parameters of transformation zones (generalized transformation parameter, the highest bandwidth in the spectrum transposition mode) and their parameters at a speed close to the speed of operation in real time conditions is shown. On the basis of the presented calculation algorithm, solutions of optimization problems are obtained to determine the generalized transformation parameter, the highest bandwidth in the spectrum transposition mode at the output of the converter in the spectrum transport mode. The presence of a periodic dependence of these parameters on the conversion zone number is shown.
