Chaotic signals have many unique properties, chaotic digital modulation technology has many advantages over traditional digital modulation technology, so it has good application value in the field of information security. In order to analyze the differential chaotic shift keying technology more comprehensively, based on the research of the DCSK, FM-DCSK and RM-DCSK differential chaotic shift keying techniques, the MATLAB simulation platform is used to simulate the balance of the different sequences and the initial values of different chaotic keying systems are used to simulate the error performance of different systems. The experimental results show that the peak of the balance of chaotic map may lead to the peak value of the system error rate. Therefore, the peak point should be avoided when the initial value of the sequence is selected. Different digital modulation techniques and chaotic mapping systems have their own characteristics, and when the reasonable parameters are selected according to the characteristics, the system performance can be optimized.
