摘　　要：提出了用于认知无线电自适应调制和资源分配的并行免疫遗传算法,并对该算法、简单遗传算法和静态调制分配算法进行了仿真.仿真结果显示,该算法具有很强的全局搜索能力和较快的收敛速度,在误码率和功率受限条件下,该算法比简单遗传算法和静态调制方式的性能更好,同时明显降低了计算复杂度。A parallel immune genetic algorithm for adaptive modulation and cognitive radio spectrum assignment was developed,and simulations are conducted to compare the parallel immune genetic algorithm method with simple genetic algorithm and non-adaptive modulation algorithm.The simulation results show that the algorithm has strong global searching capability and fast convergence speed,and it is efficient and superior to the simple genetic algorithm and non-adaptive modulation algorithm in case of limited total transmitting power and presence of notable bit error rate,while the computation complexity is reduced significantly.
