中文摘要：

为了提高认知的跳频CDMA通信系统的抗干扰性能和系统容量,论文提出了一种基于认知协同的可重新配置的三无碰撞区时频序列的构造方法,并进一步证明了构造方法的有效性,列举了构造示例和汉明相关函数的性能。这种可重新配置的时频序列构造方法可以应用到认知的、可重构通信系统中。

英文摘要：

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.
