Testing of numerical simulation methods for solid-state generators of microwave chaotic oscillations

Abstract

The models of solid-state sources of chaotic oscillations (chaos generators) of various complexity order are considered in the present paper. The investigated chaos generators are intended for transmitting devices of wireless personal communication networks. A technique for testing of numerical simulation methods of chaos generators is proposed. This technique allows to choose the most accurate numerical method for solving ordinary differential equations of chaos generators and to ensure the correctness of the obtained results. The results of numerical simulation of dependences of the output power upon the supply voltage for chaos generators of various complexity orders are presented. The obtained results allow to determine the optimal scheme of the chaos generator for receiving the required structure of the frequency spectrum and the power level of the output signal.
