讲述了最大熵估计的方法，以及dsp的实现方法，比较清楚(spoke of the estimated maximum entropy method, and the realization dsp, more clearly)

自己编的以MNV为准则设计Capon波束形成器，N=16，干扰功率分别为40dB，35dB，50dB。代码中比较了MVDR MMSE MSINR三种算法的优劣。(Own series of guidelines designed to MNV Capon beamformer, N = 16, respectively, the interference power 40dB, 35dB, 50dB. Code MVDR MMSE MSINR compare the pros and cons of the three algorithms.)

Under the circumstances of pure lag in feedback control system and the imprecision of the controlled object model, the fuzzy logic and pure lag compensation theory is used to design a Fuzzy PI-Smith control system . By the Simulink toolbox and Fuzzy logic toolbox of MATLAB, the system has been simulated. The simulation results show that the Fuzzy PI-Smith system has faster response speed and smaller overshoot than the traditional PI-Smith system.The explicit formulation of Fuzzy PI-Smith system is derived, and it lay the basis for the practical application of control algorithms.
