剔除粗大值，利用3o准则剔除坏值，然后再判断是否还有，把残差，还有其他输出来。(Eliminate gross values)

1.东西方向、南北方向均有红、黄、绿三种信号灯； 2.东西干道和南北干道，绿灯下情况通行，红灯情况下不行，黄灯情况下 慢行； 3.东西干道和南北干道交替控制； 4.实时提醒绿灯亮的剩余时间； 5.通行时间可调； 6.雾霾或夜间模式按钮按下，所有方向显示黄灯.(1. there are three red, yellow and green lights in east-west direction and north-south direction. 2. the East West trunk road and the north-south trunk road pass under the green light. 3. East and west main road and the north and South Main Road alternately control; 4. reminding the remaining time of the green light in real time; 5. the time can be adjusted; 6. haze or night mode button is pressed, all directions show yellow light.)

这是针对XC878单片机的各模块的程序，包含有LCD，UART，AD，DA以及七段数码管等。适合移植和学习。(It is for each module XC878 microcontroller program includes LCD, UART, AD, DA, and seven-segment digital tubes. Suitable for transplant and learning.)

GSM模块AT命令组装和AT命令响应解析程序。实现了自动组装标准AT命令并发送到GSM模块，同时可以提取GSM模块输出的所有AT命令，同时实现了大量AT命令响应的解析工作。主要的过程采用了Contiki的进程模型。(Making and parsing routine for AT commands of GSM module. It can automatically make standard AT commands and sent it to GSM module, while it can get all the AT commands sending GSM module, and analysis a large number of AT command responses. The main process uses a process model of Contiki.)

Energy efficiency is the most important design goal for wireless sensor networks (WSNs). In this paper, we propose an energy-efficient cooperative MIMO scheme, which combines energy-efficient LEACH (EE-LEACH) protocol and cooperative MIMO. We name it as EE-LEACH-MIMO scheme. EE-LEACH is an improved LEACH algorithm, in which the network is partitioned to sectors with equal angle for avoiding the distribution non-uniformity of cluster heads. In EE-LEACH-MIMO scheme, the location and the residual energy of each node are considered when the cluster heads for clustering and cooperative nodes for MIMO system are chosen. For comparisons, LEACH, EE-LEACH, the simple cooperative scheme with LEACH and MIMO (LEACHMIMO), and EE-LEACH-MIMO scheme are simulated. The result shows that EE-LEACH-MIMO scheme can well balance the network load, save energy and prolong the network lifetime
