Abstract

The invention discloses a multi-scroll chaotic signal generator based on a step wave function sequence. The generator comprises a basic chaotic signal generation circuit N1 and a sequence generator N2, wherein the basic chaotic signal generation circuit N1 is provided with an x signal output end, a y signal output end, a -f(x) signal input end, a -f(y) signal input end and a f(y) signal input end.The input end of the sequence generator N2 is connected with the x signal output end and the y signal output end, and the output end of the sequence generator N2 is connected with the -f(x) signal input end, the -f(y) signal input end and the f(y) signal input end. Through the sequence generator N2 for generating the step wave function sequence and the basic chaotic signal generation circuit N1,hardware is simpler and easier to implement, multiple grid multi-scroll signals are generated, the encryption strength is high, and the decoding resistance is high. Mainly used for communication encryption.

Description

technical field [0001] The invention relates to the technical field of chaotic communication, in particular to a multi-scroll chaotic signal generator based on a ladder wave function sequence. Background technique [0002] Since Lorenz discovered the first chaotic system in the 1960s, chaotic phenomena have become a new field of nonlinear circuit and system research. With the deepening of the research on chaotic phenomena, it is found that the pair of chaotic systems has the characteristics of high sensitivity and dependence on initial conditions and parameters, and unpredictability. Therefore, the generation and control of chaotic signals has become an important direction in the study of chaotic phenomena. [0003] The existing multi-scroll chaotic signal generator has a complex hardware structure, less scrolls, low encryption strength and low anti-deciphering ability. Contents of the invention [0004] The purpose of the present invention is to provide a multi-scroll c...
