【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。
[Abstract]:In order to obtain frequency-hopping sequences with excellent anti-interference and security, frequency hopping sequences are constructed by non-uniform quantization method based on quantum Logistic maps and compared with Logistic maps. The equilibrium, hamming correlation and frequency hopping interval of frequency hopping sequences are analyzed. The quantum Logistic mapping is realized on FPGA. Under the same conditions (frequency number and sequence length), this algorithm is better than Logistic mapping in terms of balance and hamming correlation. The frequency hopping interval is close to that of Logistic map, so quantum Logistic mapping can be applied to frequency hopping communication system. The corresponding anti-jamming and security are superior to Logistic mapping.
