| 摘 要： | 近几年来,在认知引擎（CE）中广泛应用遗传算法（GA）优化传输波形的各项参数,然而由于无线电波形需优化的参数和所达到的目标很多,形成了巨大的搜索空间,导致遗传算法收敛时间过长,不能满足认知无线电的实时应用。针对这一问题,提出一种快速认知无线电,通过遗传算法与案例学习结合来缩短反应时间,并进行了简单的实验仿真。仿真结果表明,快速认知无线电能够对环境进行快速自适应,算法收敛时间变短。 |
| 关 键 词： | 认知无线电 遗传算法 搜集空间 收敛时间 |

| Abstract: | Recently,the genetic algorithm(GA) has been widely used in cognitive engine(CE) for optimizing all the parameters of transmission waveform.However,the convergence time of GA is too long to satisfy real-time application of cognitive radio,due to the large search space of a large number of parameters and their possible values.To solve this problem,a rapid cognitive radio is proposed.This radio can cut down the expense of the reaction time by combining GA with a case.A simple simulation was carried out.The sim... |
