  • In order to improve the anti-interference performance and system capacity of cognitive Frequency Hopping Code Division Multiple Access (FH-CDMA) communication systems, a kind of time-frequency sequence with three no hit zone, which can be made reconfiguration based on cognitive collaboration, is presented by this paper. The sequence design method is proved effectively. A construction example is enumerated, as well as the performance of its Hamming correlation function is explained. This kind of construction method of time-frequency sequences can be made reconfiguration and applied highly in cognitive reconfigurable communication systems.
