说明：  扩频通信的实现，采用BPSK调制及相应的解调(Implementation of Spread Spectrum Communication)

This a plat for for computing NSF index in quality management of water quality.

Qpsk的性能仿真，此处用matlab语言编写(Qpsk performance simulation, matlab language used here)

蚁群算法是一种模仿蚁群行为的仿生优化算法，其实现机理包括两个基本阶段：适应阶段和协作阶段。在适应阶段，各可行解根据积累的信息不断调整自身结构，路径上经过的蚂蚁越多，信息量越大，则该路径越容易被选择：时间越长，信息量越小。在协作阶段，各可行解之间通过信息交流，以期望产生性能更好的解。(Ant colony algorithm is a mimic ant colony behavior of bionic optimization algorithm, its implementation mechanism includes two basic stages: adaptation and collaboration. In adaptive phase, the feasible solution according to the accumulated information constantly adjust their structure, path through the more the ants, the greater the amount of information, it is the easier path is chosen: the longer the time, the smaller the amount of information. The collaboration stage, through the exchange of information between the feasible solution, expecting to generate better solutions.)

This work is done by someone else. I m only uploading it to share with you.

matlab画图小程序，对初学matlab会有所帮助。。。。(matlab for figure)

The simulation provides stepper motor working clockwise and anticlockwise as well as speed control application
