Other AbstractThe invention relates to a wireless network technology, and discloses a multi-antenna cognitive wireless network channel converging method based on a permutation group. By adopting the method, a cognitive user adopting multiple antennas can realize blind convergence of channels without clock synchronization. According to the method, the characteristics of channel diversity, permutation group closure, multi-antenna concurrency and the like are sufficiently utilized when a frequency hopping sequence is designed, to realize circular splicing based on a permutation group obtained from a regular polyhedron or a regular polygon by rotating different angles according to different types of symmetry axes; different antennas can independently generate a frequency hopping sequence according to different laws and switch channels, the sequence generating mode is diverse and flexible, and parallel search can ensure that the cognitive user can realize deterministic convergence with other cognitive user as quickly and as much as possible within limited time; therefore, the method is an efficient blind channel converging method which has wide applicability and can be applied to a large-scale wireless network.
