this file contain some useful common communication matlab m tool. like QAM PSK and simulation of receiving noisy signal

the code simulates the MIMO-OFDM spatial multiplexing with successive interference cancellation

时间窗物流配送车辆路径问题(Vehicle Routing Prob- lem ,VRP)最早是由Dantzig 和 Ramser 于 1959 年首次 提出的.该问题的研究目标是 ,对一系列的顾客需求点 设计适当的路线 ,使车辆有序地通过,在满足一定的约 束条件(如货物需求量、发送量 、交发货时间、车辆容量 限制 、行驶里程限制 、时间限制等)下,达到一定的优化 目标(如里程最短、费用最少、时间尽量少、车队规模尽 量小 、车辆利用率高等).(With the development of diversified demand, the time demand of customers becomes more and more important in logistics distribution. Obviously, lowering distribution cost, distributing goods timely, improving the service quality, optimizing logistics distribution vehicle routing problem with Time Windows (VRPTW) is exigent to corporations.)
