Abstract

The invention relates to the technical field of communication, in particular to a frequency hopping communication method and device, a storage medium and electronic equipment, and the frequency hopping communication method comprises the steps: determining the transmitting power of a transmitting end according to the interference power transmitted by a receiving end; determining a signal-to-noise ratio of the receiving end according to the transmitting power and a channel attenuation coefficient; determining a probability vector for generating a frequency hopping sequence according to the signal-to-noise ratio and a preset solution optimization problem; mapping a base sequence into a frequency hopping sequence according to the probability vector; controlling the transmitting end and the receiving end to perform synchronous frequency hopping through the frequency hopping sequence; and controlling the transmitting end to transmit a signal to the receiving end at the transmitting power. According to the frequency hopping communication method, detection, eavesdropping and interference of other devices can be avoided through continuous frequency switching, and the reliability and concealment of a communication system are improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a frequency hopping communication method and device, a storage medium, and electronic equipment. Background technique [0002] With the rapid development of computer performance, especially the rise of quantum computing, the method of information transmission relying on traditional cryptography is becoming more and more easy to be cracked and monitored. Therefore, with the development of information technology, covert communication has been widely used in the field of information security. Applications. [0003] Covert communication technology realizes the covert and safe transmission of information because of the low detection probability of its transmission signal. In recent years, covert communication has become a research hotspot in secure communication. Compared with information hiding and signal parameter hiding, covert communication starts with signal concea...
