代码说明:

带时间窗的车辆路径问题(Vehicle Routing Problem with Time Windows, VRPTW)是对物流配送管理的核心问题——配送车辆调度 的问题抽象,其是在基本VRP基础上添加了时间窗约束衍生而来的, 可以将VRPTW描述为:使车辆从站点出发服务用户,完成用户需求 后仍返回站点,规定每个用户只能被一辆车服务且仅服务一次,且对 用户的服务必须在用户事先指定的时间窗内进行,问题的优化目标是 如何选择适当的路径,使得在满足以上约束条件的情况下,完成全部 需求花费的总成本最小或总利润最大。

  • 新的符号定时和载波频率同步算法
    一种新的符号定时和载波频率同步算法,该算法将OFDM符号分成几部分。它使用相关性和积累在几个OFDM 符号获得估计函数。当部分的长度小于ISI自由地区,该算法可以识别它。然后估计的最优符号定时和载波频率偏移可以获得。计算机仿真结果表明,该算法不仅可以跟踪时变信道变化但也有较小的MSE比ML估计算法。(A new symbol timing and carrier frequency synchronization algorithm is presented and the algorithm divides the OFDM symbol into several parts. It uses correlation and accumulation in several OFDM symbols to acquire estimation function. When the length of part is smaller than that of ISI free region , the algorithm can distinguish it. Then the estimation of optimal symbol timing and carrier frequency offset can be acquired .The computer simulation results show that the proposed algorithm not only can track time varying channel change but also has smaller MSE than that of ML estimation algorithm.)
