人耳识别的主成分分析MATLAB算法M文件(PCA)

电动私家车的充电负荷计算，蒙特卡洛法，电动汽车充电负荷模型(Electric Car Charging Load Calculation, Monte Carlo Method, Electric Vehicle Charging Load Model)

说明：  用sinc插值和最近领域插值完成距离弯曲校正的完整程序和几篇弯曲校正文章(Using sinc interpolation and nearest domain interpolation to complete the complete program and several bending correction articles)

最近用Mega128写了一个128点FFT程序，浮点运算，加汉宁窗。由于窗函数和旋转因子通过查表得到，所以速度还可以，程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)

对回转支承信号的处理，对时域内特征值得提取和主成分分析，计算第一主成分(For slewing ring signal processing, time domain feature extraction and principal component analysis is worth calculating the first principal component)

传统的解相干方法主要有空间平滑和子空间拟合两类,但这些方法或者阵列利用率低或者计算复杂度高,因此寻求计算量小且阵列利用率高的解相干测向方法有重要意义.该文基于前后向矢量重构理论,(The traditional decoherence methods spatial smoothing and subspace fitting into two categories, but these methods or array utilization rate is low or high computational complexity and therefore seek small amount of calculation and array of high utilization coherent finding method is important. This paper is based on the vector before and after Reconstruction,)

BPSK调制解调，采用升余弦波形成形，误码性能分析(BPSK modulation and demodulation, the use of raised cosine waveform shaping, error performance analysis)

说明：  基于标准模型的人脸识别程序，里面有一些小程序。(Face recognition program based on the standard model, which has some small programs.)

edge detection using gabbis

M/M/1 模型,主要用来求解单对单服务台的模型，过程比较简介，适合任何分布(M/M/1 model, mainly used to solve the one-on-one help desk model, the process is relatively brief, suitable for any distribution)
