摘要:

针对甚高频数据链频率资源紧张和通信干扰问题,提出一种改进型邻域禁忌退火算法进行频率资源调度和优化分配。首先构建基于软频率分配规则框架的移动蜂窝通信模型,设置频谱分配矩阵初始解;然后以甚高频服务区网络的系统干扰惩罚值最小为优化目标,根据适应度的变化选择相应的邻域生成策略生成候选邻域解,通过候选邻域解执行迭代优化,并依据Metropolis准则实现降温过程;最后获得优化后的频率分配矩阵。与遗传算法、禁忌搜索算法、模拟退火算法等传统方法相比,所提方法在收敛速度、系统干扰、吞吐量等方面均呈现出较好的性能。

Abstract:

To address the issues of tight frequency resources and communication interference in very high frequency data links, an improved neighborhood tabu annealing algorithm is proposed for frequency resource scheduling and optimal allocation. Firstly, a mobile cellular communication model based on the soft frequency allocation rule framework is constructed, and the initial solution of the spectrum allocation matrix is set. Then, taking the minimum system interference penalty value of the very high frequency service area network as the optimization objective, the corresponding neighborhood generation strategy is selected according to fitness changes to generate candidate neighborhood solutions. Iterative optimization is carried out via the candidate neighborhood solutions, and the cooling process is implemented based on the Metropolis criterion. Finally, the optimized frequency allocation matrix is obtained. Compared with traditional methods like the genetic algorithm, tabu search algorithm, and simulated annealing algorithm, the proposed method shows better performance in terms of convergence speed, system interference, and throughput.

Key words: very high frequency data link, frequency allocation, soft frequency allocation rule, interference optimization, improved neighborhood tabu annealing algorithm
