利用GA來模擬鳥群尋找食物的行為，方法就是找尋距離食物最近的鳥之周圍區域及根據自己本身飛行的經驗判斷食物的所在(The use of GA to simulate the behavior of the flock in search of food, the methodology is to find the nearest bird food from around the region and according to their own experience of flying to judge the location of food)

因此假设了一种机动目标模型：初始匀速直线阶段、匀速圆周运动阶段、返回匀速直线阶段，在此过程中线速度大小?v?保持不变。利用扩展卡尔曼（extended kalman filter, EKF）滤波算法进行定位跟踪，仿真结果表明，该假设模型既符合机动实际，又便于数学处理，并且滤波算法过程稳定，具有较快的收敛速度和较高的定位精度，提高了机动目标跟踪的精度和系统的实时性。(This paper proposes a maneuver target model: the initial phase of the uniform linear, uniform circular motion stage, returning to uniform linear stage, and the size of the line speed v remaining unchanged in this process. The extended Kalman filter (EKF) was used to track position, and simulation results show that the model is in line with the actual motor and easy to deal with the mathematics. The algorithm is stable and has rapid convergence rate and high positioning accuracy to improve the accuracy of the mobile target tracking and real?time system.)

包括了无线通信中频繁使用的一些基本的信源编码方式,如QPSK,MASK等.(including wireless communications frequent use of some of the basic source coding methods, such as QPSK, such as MASK.)

Multiple antenna’s at the receiver (aka receive diversity) improves the bit error rate (BER) performance. In this post, let us try to understand the BER improvement with receive diversity.
