说明: 提出了正交频分复用(O FDM ) 系统中一种新的载波频偏估计算法L 载波频偏估计过程可分
为获取和跟踪, 其中, 获取过程和时间同步是同时完成的L新算法可实现的最大载波频偏获取范围
是整个信号带宽的一半L新的跟踪算法是一个最大似然算法, 在加性白噪声高斯信道(AW GN ) 下,
当N (训练序列长度的一半) 等于128 时, 其性能比Schm idl 算法提高约7127 dB 在多经信道下, 当
信噪比不是很高时, 新算法仍具有优势L(new carrier f requency offset est imat ion scheme in o rthogonal f requency

遗传算法GA
matlab 遗传算法GA,粒子群算法PSO,蚁群算法AS 前段时间上智能计算方法实验课上,自己做的程序。帖到这里,希望有人能改进它们,交流经验这样更有价值。 遗传算法解决最小生成树问题,PURFER编码。 粒子群算法做无约束最优化问题。 蚁群算法解决TSP问题。 (matlab genetic algorithm GA, particle swarm optimization PSO, some time ago on the ant colony algorithm intelligent calculation AS experimental course, make their own programs. Posts here, I hope someone can improve their exchange of experience is more valuable. Genetic algorithm to solve minimum spanning tree problem, PURFER code. Particle Swarm do unconstrained optimization problems. Ant colony algorithm to solve TSP problem.)
