基于MATLAB的Nakagami衰落信道仿真与分析(MATLAB-based Nakagami fading channel simulation and analysis)

knn是一种分类算法，它是基于matlab的一种模式识别的经典算法，一般适用于样本个数较小的样本分类。(KNN, it is classification algorithm based on matlab a pattern recognition of the classic algorithm, generally applied in sample number of smaller sample classification. )

路面裂缝检测识别系统设计，希望对大家有所帮助，相互学习。(Pavement Crack Detection Recognition System)

说明：  用VHDL语言编写的FFT程序，有些参考价值哦(VHDL prepared by the FFT procedure, some reference value oh)

Currently systems and dynamics research is ongoing in modeling and identification primarily for controller design, state estimation and fault detection/diagnosis. With accurate and precise system model identification, no aspect from controls to fault detection should have to employ unreasonable architectures/strategies to lower production cost and to expand the operational life of the turbine

贝叶斯估计，最小二乘法，递推最小二乘法，梯度校正法，增广最小二乘法进行系统辨识(Bayesian estimation, least squares, recursive least squares method, the gradient correction method, the augmented least squares method for system identification)

用rayleighchan 函数仿真时要注意最后要做相位补偿（此问题是导师发现的） 程序步骤： ~产生随机序列 ~产生瑞利信道 ~调制 ~记忆信道特征 ~信号通过信道 ~相位补偿 ~加高斯噪声 ~解调 ~计算仿真误比特率 ~计算理论误比特率 ~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)

在不加噪声的情况下利用PSO（粒子群算法）辨识NARMAX模型(In the case without noise, using PSO (PSO) model identification NARMAX)

光在格子中传播,前30为有格子，后35为无格子，描述其轨迹(propogaton in lattice for the first 30,there be in lattice and the nex 35 thera is no lattice)

This package enables Gaussian process prediction with very large sample sizes with a much smaller computational burden than many existing methods.
