自适应跳频受约束的信令跳变序列设计

Design of Constrained Signaling Frequency Hopping Sequence in Adaptive Frequency Hopping Radio

信令能否安全可靠地传输是自适应跳频电台性能好坏的关键。为了提高自适应跳频电台信令传输的安全可靠性,该文在分析了无约束信令跳变序列与宽间隔信令跳变序列抗部分频带干扰的性能与局限性的基础上,提出了一种受约束的信令跳变序列,并给出了其详细的构造过程。理论分析与计算机模拟结果均表明所设计的受约束的信令跳变序列与前两种信令跳变序列相比在抗部分频带干扰方面有一定的性能增益。

Signaling transmission is the key technology for adaptive frequency hopping radio. In order to improve its safety and reliability, this paper provides a constrained signaling frequency hopping sequence by analyzing the performances and the limitations of the unconstrained signaling frequency-hopping sequence and the wide gap signaling frequency hopping sequence in fractional band jamming. Theory analysis and the simulation results show that the performance of the proposed sequence is better than those of the former two sequences.
