Abstract

The present invention provides a carrier frequency hopping communication method, device, system, equipment and storage medium, including: converting information to be transmitted into a frequency hopping signal according to a preset adaptive cyclic pruning code group, wherein the automatic The adaptive cyclic puncturing code group is a frequency hopping pattern code group obtained by performing cyclic shift and selection according to the interference probability of the available frequency points in the pseudo-random code group. The interference probability of the available frequency points is obtained by performing spectrum sensing and obtained after interference detection; sending the frequency hopping signal to a wireless channel, so that the receiving end can de-hop the frequency hopping signal according to the adaptive cyclic puncturing code group. The technical scheme of the present invention can reduce the problem of interference between users in a multi-user communication system and improve the communication quality.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a carrier frequency hopping communication method, apparatus, system, electronic device and non-transitory computer-readable storage medium. Background technique [0002] With the development of communication technology and the continuous popularization of 4G and 5G networks, while communication technology is developing towards high speed and long distance, the demand for spectrum resources is gradually increasing. In the related art, the available frequency band for wireless communication is relatively fixed, and the spectrum resource is very limited, which leads to a relatively tight user capacity. [0003] Frequency hopping technology is a communication method that uses code sequences for multi-frequency frequency shift keying. Its working principle is that the carrier frequency of the transmission signal of the sender and the receiver changes discretely a...
