Description

technical field [0001] The invention relates to a signal generator, in particular to a special nonlinear system chaotic signal generator under the chaotic model of a memory system. Background technique [0002] Ordinary signal sources can generate periodic signals with different waveforms, and have been widely used in the field of information engineering. The characteristic of periodic signal is that it is convenient for the synchronization of modulation and demodulation, but it is not conducive to the requirements of special fields such as information encryption. Chaotic signals have the characteristics of inherent randomness, initial value sensitivity, broadband, ergodicity, and boundedness, and can generate broadband signals similar to white noise. Therefore, chaotic signals have a wide range of applications in the fields of information encryption, secure communication, and chaotic radar. prospect. The chaotic signal source is an important part of the modulation and dem...
