摘要
论文仿照蓝牙跳频序列的生成算法,构造出一种新的超长周期的跳频序列。经过详细的性能分析表明,新构造的跳频序列同蓝牙跳频序列相比,密钥量从227提高到264;平均跳频间隔从26提高到111;平均汉明相关从0.012 7降低到0.003 9,较好地满足了跳频序列的设计准则,适合在军事跳频通信上使用。
A family of long period FH sequences in imitation of Bluetooth FH sequences is presented in this paper. The properties of the family of FH sequences are analyzed. Compared with Bluetooth FH sequences, they increase the keys from 2^27 to 2^64 and the average FH gap from 26 to 111 and reduce the Average Hamming Correlation from 0. 012 7 to 0. 003 9, thus meeting the FH sequence design criteria and providing a basis for possible military communication applications.
