这是一个关于人脸识别的MATLAB程序。。。。。。。(face detection)

WAVELET IMAGE USING MATLAB

当线性代数联立方程组的系数矩阵为三对角阵T时，可将T分解为主对角元素为1的下三角阵L和另一个右三角阵R的积。(Simultaneous linear algebraic equations when the coefficient matrix is tridiagonal matrix T, can break down the main diagonal elements of T 1 of the lower triangular matrix L and the other right-triangular matrix R of the product.)

Phase-shift keying (PSK) is a modulation process whereby the input signal, a binary PCM waveform, shifts the phase of the output waveform to one of a fixed number of states. The demodulation process can be divided into three major subsections, as shown by Figure 4. First, since the incoming waveform is suppressed carrier in nature, coherent detection is required. The methods by which a phase-coherent carrier is derived from the incoming signal are termed, carrier recovery, and will be covered first.

1、对给出的数字0、1序列进行BPSK调制,调制成正负极性，并进行傅里叶变换. 2、滚将升余弦窗设计(1、making BPSK modulation for given 0、1 data serial.And make FFT change. 2、Raised-cosine window)
