control

It is BER vs SNR codes for BPSK and 4QAM

利用经典music算法，旋转不变子空间算法，实现对雷达到达方向角的估计，并分析了信噪比对算法的影响。(The classical music algorithm and rotation invariant subspace algorithm are used to estimate the radar arrival angle and the effect of SNR on the algorithm is analyzed.)

该程序实现灰度图像分段线性变换，Matlab实现(Gray-scale image of the process to achieve sub-linear transformation, Matlab to achieve)

PID 控制算法及扩展算法的仿真代码，建议学习控制的同志参阅一下(PID control algorithm and the expansion of the simulation algorithm code, the proposed learning control comrades see what)

这是一个用极大似然函数估计狄里克莱分布的matlab程序(This is a great likelihood function using the estimated Dirichlet distribution matlab program)

说明：  本程序包设计了一个利用Matlab编写的基于Kalman Filter的Target Tracking仿真器，可用于目标跟踪的仿真实验。(The design of a package written in Matlab, Kalman Filter for Target Tracking based simulator can be used for target tracking simulation.)

波束形成就是从传感器阵列重构源信号。（1）、通过增加期望信源的贡献来实现；（2）、通过抑制掉干扰源来实现。经典的波束形成需要观测方向(期望信源的方向)的知识。盲波束形成试图在没有期望信源方向信息的情况下进行信源的恢复(From sensor array beamforming is reconstructing source signal.(1), by increasing the expected source contribution to achieve (2), by suppressing interference sources.Classic beamforming need observation direction (expected source direction).Blind beamforming is trying to not expect source direction information of source of recovery)

粒子群算法（PSO）优化BP神经网络，用来进行非线性的校正，效果良好(Particle swarm optimization (PSO) to optimize BP neural network, used for non-linear correction, to good effect)
