说明：  该函数可以实现在mimo信号传输时的波束矩阵，尽可以实现在线性接收机的情况下可以达到最大似然的性能，从而大大简化接收机的设计。(This function can be achieved when the signal transmission in mimo beam matrix can make the case of linear receiver can achieve the maximum likelihood performance, which greatly simplify the receiver design.)

A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images.
