source code for pattern classification k nearest neighbor source code

此程序差分空时分组码编码程序,是基于正交的(Differential space-time block coding process, is based on orthogonal)

说明：  This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB

用Ziegler--Nichols整定公式来求P,PI,PID的个参数，其中Gc是校正器的传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量vars为带迟滞--惯性环节模型的KT τ(With Ziegler- Nichols tuning formula to seek P, PI, PID' s parameters, which Gc is the corrector transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters vars as with hysteresis- inertia model of the KT τ)

频率估计中的ESPRIT算法的matlab实现(Frequency estimation in the realization of ESPRIT algorithm matlab)

this is a matlab book in this tutorial u learn matlab

支持向量机的混沌是假序列预测研究，支持最小二乘法的向量机(SVM is a false prediction of chaotic sequence, least squares support vector machine)

matlab设计教程，主要是信号处理的代码实例(matlab design tutorials, mainly signal processing code examples)

本程序为仿真光学CCD进行全息成像的仿真程序，对于理解全息成像有一定帮助(The program for the simulation of holographic optical CCD imaging simulation program, for holographic imaging understand some help)

说明：  信号的希尔伯特变换 可以提取信号的顺时针夫 瞬时相位 瞬时频率(Hilbert transform of signal can extract the instantaneous frequency of clockwise instantaneous phase of signal)
