Abstract

The invention relates to a weak signal parallel communication method based on a Duffing-Chen chaotic system. The method comprises the steps of forming eight groups of communication devices by utilizing eight transmitters and eight receivers, transmitting sinusoidal wave electric signal by selecting partial transmitters, receiving an output 5V voltage signal of the sinusoidal wave electric signal by utilizing the eight receivers, outputting 0V voltage signals when the sinusoidal wave electric signal is not received, converting eight 5V or 0V voltage signals to numbers 1 and 0, forming a group of 8-digit binary numbers, inputting the 8-digit binary numbers into a computer, converting the 8-digit binary numbers to an English letter or an Arabic number, and completing one-time communication by recognizing the English letter or the Arabic number. The method has advantages of high sensitivity, high interference resistance and the like.

Description

technical field [0001] The invention relates to the field of electronic signal communication, in particular to a weak signal parallel communication method based on Duffing-Chen chaotic system. Background technique [0002] Internationally used signal communications each have their own characteristics and have their own advantages in different applications. In weak signal communication, the traditional method simply amplifies the signal for detection and identification, so the anti-interference ability is weak, and too weak sine wave signal cannot be identified, and the communication effect is not good. At present, people have verified the feasibility of using the duffing oscillator to detect signals. However, people only use the chaotic system to detect weak signals, but do not use it for communication, which still cannot meet the needs of society. Contents of the invention [0003] The purpose of the present invention is to provide a method for parallel communication of...
