| 摘 要： | 为了最小化多用户OFDM系统的发射功率,提出利用文化算法搜索最优的子载波和比特分配方案.在传统的进化算法基础上引入了指导搜索的信仰空间,使搜索效率更高,同时使得优化目标与优化变量都比较容易数值定量化.对文化算法与遗传算法、多用户自适应OFDM算法进行仿真比较,结果表明:文化算法在迭代次数上小于遗传算法,收敛性显著提高,... |

| Abstract: | To minimize the transmitting power in multiuser Orthogonal Frequency Division Multiplexing (OFDM) system, a program using Cultural Algorithm (CA) to search the subcarriers and bit allocation was proposed. Based on the traditional evolutionary algorithm, a belief space was introduced to guide the search. Thus, the search is more efficient; meanwhile, relatively the optimizing objectives and numerical variables are easily quantified. In comparison of the CA with Genetic Algorithm (GA) and Multiuser Adaptive O... |
