四轴飞行器(实现平衡调节)
应用背景通过遥控器可以控制四轴的姿态,同时四轴的姿态也可以通过蓝牙的数据传输,从上位机观测四轴的姿态。在这里我们通过调节PID的参数来完成对四轴的控制,而姿态的解析算法则是通过IMU算法来完成,用四元数进行计算,方便计算。 关键技术编程方式采用C语言编程,主控芯片采用STM32,主频速度可以达到72M,控制周期为2ms,在算法中,控制算法使用了PID控制算法,在调节参数时,先调节PD,一个是回复里,一个是阻尼力,再调节I,消除静态误差,从而使得四轴飞行器可以很稳地飞上高空,未来打算加上定高。

这是一个支持多位数运算(可以达到几百位的长整数)的数类,名字叫Long,它是从long类发展过来的,但比原来的long类功能多。Long类可以和原有的double,long等等数据类型混合运算-This is a multi-digit support operations (which may reach hundreds of long integers) to a number of named Long, it is long from over the type of development, but more than the original multi-functional long. Long classes can be double the original, long data types, etc. Operational mixed

Pilot Contamination Reduction
应用背景This paper considers the problem of interference mitigation in multi-cell multi-antenna time division duplex (TDD) wireless systems for downlink transmission. An efficient way to obtain channel state information (CSI) at the base station is by using uplink pilots and reciprocity of the downlink channel.
At the same time, it has been shown that pilots from different cells contaminate each other, resulting in corruption of precoding matrices used by base stations, and high inter-cell interference. This paper studies the effects of shifting the location of pilots in time frames used in neighboring cells, and its effectiveness in obtaining better channel estimates, and, thereby, inter-cell
interference reduction.关键技术Wireless cellular network designs with multiple antennas have been adopted by several modern wireless systems, which aim for high throughput as well as high
