Problems solved by technology
As the number of access devices and the demand for communication rates continue to grow, intersymbol interference caused by interfering signals in the frequency band and multipath effects will seriously affect communication quality. Furthermore, multipath propagation phenomena will lead to frequency selective fading , if the communication frequency is at the frequency point of deep fading, the received signal energy will be greatly attenuated, and the communication quality will be sharply reduced
[0003] Fixed-frequency communication is easy to be captured and interfered with. Traditional fixed-frequency communication methods such as time-division multiple access and frequency-division multiple access are not effective in anti-interference and anti-fading
The frequency hopping communication system can effectively resist fixed frequency interference through carrier frequency hopping, but there are still narrowband interferences at some frequency points in the frequency hopping communication system

The invention provides a frequency hopping communication method, device and system, equipment and a storage medium. The frequency hopping communication method comprises the following steps: sending a first frequency hopping signal to a receiving end according to a first pseudo-random code block; after feedback information that data received at a first frequency point cannot be de-hopped is fed back by the receiving end, the first frequency point is deleted from the first pseudo-random code block, a second pseudo-random code block is generated, and the first frequency point is any available frequency point in the first pseudo-random code block; and sending a second frequency hopping signal to the receiving end according to the second pseudo-random code block. According to the technical scheme, narrow-band interference can be reduced, and communication quality can be improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a frequency hopping communication method, device, system, electronic equipment and non-transitory computer-readable storage medium. Background technique [0002] Tactical ad hoc network is an important means of communication support for future wars, with the characteristics of flexibility, easy deployment, and swarm intelligence. As the number of access devices and the demand for communication rates continue to grow, intersymbol interference caused by interfering signals in the frequency band and multipath effects will seriously affect communication quality. Furthermore, multipath propagation phenomena will lead to frequency selective fading , if the communication frequency is at the frequency point of deep fading, the received signal energy will be greatly attenuated, and the communication quality will decrease sharply. [0003] Fixed-frequency communication is e...
