【摘要】：将方法无线电和应用数学的原理引入多用户差分跳频网络,提出基于拉丁方的认知差分跳频自适应频率集方法.该方法在认知后得到可用频谱信息的基础上,将跳频频率集划分为频率子集,按照动态生成的拉丁方将频率子集动态分配给网内用户,使同一时隙内用户的频率子集正交,从而抑制多用户网络的多址干扰,提高抗部分频带干扰以及多音干扰性能.仿真结果显示该方法较传统多用户差分跳频网络可以显著提高多址性能与抗干扰性能.
[Abstract]:The principle of method radio and applied mathematics is introduced into multi-user differential frequency hopping network, and a Latin square based cognitive differential frequency hopping adaptive frequency set method is proposed. Frequency hopping frequency sets are divided into frequency subsets, frequency subsets are dynamically allocated to users in the network according to dynamically generated Latin square, so that the frequency subsets of users in the same time slot are orthogonal, so as to suppress the multiple access interference of multi-user networks. The simulation results show that the proposed method can significantly improve the performance of multiple access and anti-jamming compared with the traditional multi-user differential frequency hopping network.
