fft calculation of any input signal

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

说明：  感知无线电中空闲频谱感知的双次协作检测算法仿真(double cooperative detection in spectrum holes)

高阶谱估计的函数方程,很有用处,用于检测被高斯信号淹没的信号(higher order spectral estimation function equation, useful for the detection of Gaussian signal was submerged signal)

卡尔曼滤波对温度的估计测量,用两种不同程序实现此功能。(Calman filter for estimation of temperature measurement)

matlab的程序，光伏电站中太阳能电池的仿真模型，希望有用(matlab program, the simulation model of the solar photovoltaic power plants, I hope useful)

消除50Hz工频干扰数字滤波器的设计,设计思路很巧妙，程序很小很好用(Eliminate the 50Hz frequency interference digital filter design, design ideas is very clever, good program is very small)

长方形房间混响仿真代码，可设置声源和收听者的位置。(A simulation of the acoustics of a simple rectangular prism room has been constructed using the MATLAB m-code programming language.)

说明：  异步电机适量控制的仿真，并用卡尔曼滤波做了无速度传感器(Simulation of the appropriate amount of asynchronous motor control, and using Kalman filter to make a speed sensor)

Beginning with an introduction to 802.11b in general, 802.11 Security gives you a broad basis in theory and practice of wireless security, dispelling some of the myths along the way. In doing so, they provide you with the technical grounding required to think about how the rest of the book applies to your specific needs and situations. If you are a network, security, or systems engineer, or anyone interested in deploying 802.11b--based systems, you ll want this book beside you every step of the way.(Beginning with an introduction to 802.11b in general, 802.11 Security gives you a broad basis in Theor y and practice of wireless security, dispelling some of the myths along the way.
