Abstract

Aiming at the problem that traditional frequency hopping communication has insufficient adaptability to dynamic and complex electromagnetic interference environment, and in order to overcome the dependence of existing frequency hopping algorithms on common control channels and a unified clock source in distributed communication environment, this paper proposed a distributed cognitive frequency hopping algorithm based on an asymmetric clock sequence. This algorithm established a cognitive frequency hopping communication system model, analyzed the key problems in its communication process, and designed an asynchronous clock structure sequence for distributed frequency hopping communication environment. The distributed cognitive frequency hopping algorithm based on this sequence did not rely on any common control channel and unified clock source, and could achieve the effect of efficient communication anti-interference in complex electromagnetic interference environment. The experimental results show that the anti-interference performance of this algorithm is significantly better than the traditional frequency hopping communication algorithm and the existing common control channel cognitive frequency hopping algorithm for typical narrowband, broadband noise interference, partial frequency band interference and random interference.
