Firstly, it discusses the principle of adaptive interference chancellor, including broad band signal and narrow band signal; Secondly, it analysises one common algorithm used in adaptive interference chancellor, that is, LMS algorithm and its anamorphosis algorithm especially normalized LMS algorithm pointing out their relationship. After then, the paper talks about the structure and reality of canceling broad band noise in narrow band signal and narrow band noise in broad band signal and gives it's result simulation analyzing the factors affecting the power of the algorithm. In the last party, it gives the hardware design and assembly language software design using TMS32OC3 1, including the result of simulating.

An equipment for mixed use of wide-band ADSL and marrow-band cards features that associated LVDS transceiver and on-board connector are installed to ATVC card and WAN card. The high-speed wide band ADSL data line can use LVDS mode to conveniently realize the mixed use of wide-band ADSL and ordinary analog user card on narrow-band speech exchange or the ONU rack of optical network unit. It is connecessary to modify the backplate of POTS and machine rack. The existing narrow-band device can be upgraded to have wide-band access function.

本发明提供了一种宽带ADSL和窄带用户板混插的装置，通过在ATUC板和WAN板上提供相应的LVDS收发器和板上连接器，高速宽带ADSL数据通过背板外LVDS走线方式，可以在普通窄带话音交换机或接入网光网络单元ONU的机框上，方便地实现宽带ADSL与普通模拟用户板之间的混插，这种方法不需要对窄带话音POTS的背板和机框作任何改动，即可实现窄带到宽带的平滑过渡，对已有窄带设备可提供随时升级为宽带数据接入功能的方法及设备。

Under the linear relationship between narrow band and broadband albedos, according to the same time MODIS image data of narrow-band albedo, multiple linear regression equation was established to achieve narrow-band to wide-band Albedo retrieving.

在窄波段反照率与宽波段反照率之间存在线性关系的前提下，通过与相同时段的MODIS图像数据的窄波段反照率建立多元线性回归方程，构建回归模型，实现窄波段到宽波段的反演。
