能量检测，根据以URKOWITZ 在1967年发表的能量检测文章以及Digham 2003、Ghasemi 2007发表的一系列文章为参考， 在AWGN信道中，给定SNR下，先产生一个原始信号（单音或者BPSK基带信号），然后叠加高斯噪声， 再进行能量检测(Energy detection, according to URKOWITZ the energy released in the 1967 test articles, and Digham 2003, Ghasemi 2007 series of articles published as a reference, in the AWGN channel, for a given SNR, the first generating an original signal (mono or BPSK baseband signal), and then superimposed Gaussian noise, then the energy detection)

对信号进行快速Fourier变换，求谐波波幅值及谐波相角值(Fast Fourier transform of the signal, find the harmonic amplitude and phase angle of the harmonic value)

多视图几何三维重建程序，经典算法matlab，非常全，对三维重建很有帮助。(Multi-view geometry of three-dimensional reconstruction procedure, the classical algorithm matlab, very wide, very helpful for three-dimensional reconstruction.)

function [x, hist] = secant(x, f, tola, tolr) SECANT This a secant code with no line search. This code terminates on small relative-absolute errors function [X, HIST] = SECANT(X, F, TOLA, TOLR) Inputs: X = initial iterate F = function TOLA = absolute error tolerance TOLR = relative error tolerance Output: X = approximate result

说明：  实现了PCM编码和译码的功能，适合各个Matlab版本运行。(Achieve a PCM encoding and decoding functions for each version of Matlab to run.)
