AI Technical Summary
Existing frequency-hopping communication systems cannot adjust spectrum allocation in a timely manner according to the channel environment, resulting in low spectrum resource utilization and insufficient anti-interference capability.
By incorporating cognitive radio technology into frequency hopping sequence design, a cognitive frequency hopping sequence is generated. A pseudo-random sequence is generated using the device ID and system time TOD. Combined with the spectrum hole results and the number of available frequency slots, a frequency hopping code with path protection is generated. The frequency is adjusted in real time to avoid interference and utilize spectrum holes.
It achieves efficient utilization of spectrum resources and avoidance of interference, improves the security and communication reliability of frequency hopping paths, and enhances the ability to resist interception and decryption.
