到达时间差（TDOA）源位置估计 -------------------------------------------------- ---------- 使用麦克风信号和自由场模型之间的延迟源位置估计。 TDOA_pairs.m 估计延迟（相对于通道1）通过互相关在时域中。 TDOA_pairs_GCC.m 估计在频域中的延迟（相对于信道1）。采用广义互相关 和SCOT或PHAT（或没有）的均衡。 PHAT的建议，以避免因周期分量的含糊之处。 TDOA_to_sourcepos.m 估计源位置（距离和垂直RESP。水平偏移量）从之间的延迟 阵列麦克风信号。假设一个自由场。(Direction of arrival (DOA) estimation ------------------------------------- Direction-of-arrival estimation with a free field, far field model. Narrowband or broadband (non-coherent) processing. DOA_Bartlett.m Bartlett (delay-and-sum) steered response power. DOA_Bartlett_Octave.m Bartlett (delay-and-sum) steered response power within nth octave frequency bins. DOA_MUSIC.m MUSIC based pseudo beamform power. DOA_MUSIC_Octave MUSIC based pseudo beamform power. nth octave filtering.)

说明：  1.学习使用fft2,ifft2,fftshift,ifftshift函数。用fft2函数对”lena.bmp”做二维傅立叶变换，并显示其频谱，用fftshift函数将频谱坐标原点移动到图像中心。用ifft2函数做傅立叶反变换。（提示：显示频谱时，可以先对频谱取对数，这样可以压缩动态范围很大的频谱，获得更好的显示效果）(1. Learn to use fft2, ifft2, fftshift, ifftshift functions. With the FFT 2 function, the lena.bmp'The two-dimensional Fourier transform is performed and the spectrum is displayed. The origin of the spectrum coordinate is moved to the center of the image by using the FFT shift function. The inverse Fourier transform is done with ifft2 function. (Note: when displaying the spectrum, the logarithm of the spectrum can be taken first, so that the spectrum with a large dynamic range can be compressed to obtain better display effect.))

关于无线信道的多普勒谱 无线信道中的多普勒谱有一种经典谱请解释产生这种谱形状的机理；(1. On the radio channel of the Doppler spectrum (2) wireless channel Doppler spectrum has a classic spectrum (classic spectrum), please explain such a spectral shape of the mechanism )
