扩频因子在通信领域是我们必须要掌握的重点，本文章系统详细的阐述了扩频因子的作用，原理等，希望对大家有所帮助~(Spreading factor in the field of communication is that we must grasp the focus of this article system detailed expounds the function of spreading factor, principle and so on, hope to be of help)

这是一个优化IIR滤波器的源码,能设计出8个极点8个零点的IIR优化滤波器(This is a source optimized IIR filter can be designed eight against eight pole optimization of IIR filter)

matlab的一个公式计算源代码，非常好用的(matlabx learning materials, is a very good about the Matlab programming reference)

用cvx求解宽带最小二乘的波束形成，最新的程序，注释的地方很多，很有借鉴 (Many use cvx to solve broadband beamforming least squares, the latest program, notes the place, a very useful reference)

This Filter provides a selective mean (averaging) lter. In contrast to the standard mean lter,it preserves edges better and is less sensitive to outliers(outliers are those that are not included in the measurement taking place.In this case averaging). The lter smooths an image by taking an average over the neighbouring pixels, but only includes those pixels that have a value not deviating from the current pixel by more than a given range. The range is dened by the standard deviation of the pixel values within the neighbourhood . If the number of pixels in this range is too low (less than `Minimum Pixel Fraction ), averaging over all neighbouring pixels is performed.With the `Outlier Aware option, averaging over all neighbouring pixels excludes the center pixel.
