GPS信号捕获 指标是signalpower=-185dBW，此时可以进行室内定位(GPS signal acquisition indicator is signalpower =-185dBW, indoor positioning can be performed at this time)

说明：  A*算法；路径规划；matlab栅格法;全局路径规划算法需要画栅格地图，添加障碍物，起点，目标点，本例程可以生成地图(path planning;The global path planning algorithm needs to draw a raster map, add obstacles, starting points, target points, this routine can generate a map)

QPSK信号通过Rayleigh信道，并计算出误码率(QPSK signals go through Rayleigh channel)

根据居民历年用电量，采用lm算法，对居民未来电量进行短期预测，实现供电部门对电力规划的部署。(According to the electricity consumption of the residents, the LM algorithm is used to predict the future electricity consumption of the residents in short term, so as to achieve the deployment of the power supply department to the electric power planning.)
