摘　　要：基于最佳接收和最大化利用现有空闲频谱资源的思想,提出一种认知跳频系统的实现方案,然后在此基础上,重点对其在单频、多频和部分频带干扰下的抗干扰性能进行了研究。理论分析和仿真结果表明,在理想同步情况下,该认知跳频系统较常规跳频有更强的抗干扰能力。Based on the thoughts of the optimal receiving and maximization existing free spectrum resource, an implementation scheme of cognitive frequency hopping system is designed. Then on this basis, the anti-jamming performance of the system is studied in case of single-frequency interference, multi-tune interference and partial-band block interference. The theoretic analysis and simulation show that under the condition of ideal synchronization, cognitive frequency hopping has stronger anti-jamming ability than common FH.
