摘　　要：为了获得具有优异抗干扰性和安全性的跳频序列,基于量子Logistic映射,对比于Logistic映射,通过非均匀量化的方法来构造跳频序列;分析了跳频序列的平衡性、汉明相关性、跳频间隔,在FPGA上实现了量子Logistic映射。实验结果表明,在相同的条件下(频率数目和序列长度),本文算法在平衡性、汉明相关性方面都优于Logistic映射,跳频间隔和Logistic映射数值接近。基于此,可以将量子Logistic映射应用于跳频通信系统,相应的抗干扰性和安全性优于Logistic映射。For getting a better hopping sequence with anti-interference and safety,compared with logistic map,based on the quantum logistic map and takes the nonuniform quantization method,frequency hopping sequencs was produced. The balance,hamming correlation and frequency hopping interval were analyzed and realiezed on the FPGA. Performance analysis and experiment results show that the sequence performs better than logistic map on balance and hamming correlation,has the same performance on frequency hopping interval. It＇s concluded that the quantum logistic map can applied to frequency hopping and has a better performance of anti-interference and safety over logistic.
