PWM

通过MATLAB来计算阵列天线，包括线性阵列，平面阵列，还有圆形阵列(Calculated by MATLAB array, including linear arrays, planar array, as well as circular arrays )

Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

最小二乘法椭圆拟合 fit_ellipse( x,y,axis_handle ) x，y为坐标点 适用于一般方程哦。好用(Least squares ellipse fitting fit_ellipse (x, y, axis_handle) x, y for the coordinates of points applicable to the general equation Oh. Use)

将方波周期信号展开成傅里叶级数并生成3次，5次，8次，10次谐波(Expand the square wave into a Fourier series of periodic signal and generates 3 times, 5 times, 8 times, 10 times harmonic)

说明：  初始对准是捷联惯导系统进行导航的前提，初始对准的好坏将直接影响到系统的导航精度。捷联惯导系统(SINS)初始对准的本质是确定载体的初始姿态。(The initial alignment of strapdown inertial navigation system is the premise for navigation, initial alignment will directly affect the quality of the navigation system precision. Strapdown inertial navigation system (SINS) is to determine the nature of the initial alignment of the initial attitude of the vehicle.)

利用时域相关定理结合FFT完成相关函数计算源程序，包括时延估计。(Theorems time domain and FFT to complete the correlation function computing source, including delay estimation.)

说明：  能实现第四代移动通信系统中的关键技术MIMO-OFDM，是一个两发两收的MIMO系统(To achieve the fourth generation mobile communication system in key technology MIMO-OFDM, is a collection of two rounds of two MIMO systems)
