摘要
跳频序列发生器是跳频通信系统的核心部件,寻求理想的跳频序列是研究跳频通信的重要课题之一。通过对RS码跳频序列相关技术的研究,改进了基于RS码宽间隔非重复跳频序列的优化方法,利用Matlab软件进行了仿真,并绘制出了某个跳频序列的汉明相关性。计算结果表明,该方法克服了对偶频带法产生的宽间隔的跳频序列随机性较差的缺点,提高了整个跳频序列的平均间隔,满足相邻频率值大于某个固定的常数,同时也满足宽间隔非重复跳频序列族的理论界限。
Frequency hopping sequence generator is a core component of frequency-hopping communication system,covered the ideal frequency hopping sequence is one of the important issues for hopping communication. The related technology about the FH sequence in RS code is analyzed,a frequency-hopping sequence of Hamming correlation is drawn out by Matlab. The results show that the optimization method and average interval of non-repeating FH sequences is improved with given minimum gap based on RS code and the disadvantages of the poor randomness is overcame which is brought forward by FH sequence with given minimum gap based on the dual fre-quency band method,meets that the interval of adjacent frequency more than a fixed value,and satisfy the theoretical bounds on families of non-repeating FH sequences with given minimum gap.
