By exploring the phase information among symbols of the Direct Sequence Spread Spectrum (DS-SS) signal, a novel de-noising approach, used in low signal noise ratio environment, is presented.
The precision ratio of solvent was confirmed, and feasible spread solvent was selected.
确定了溶剂的精确配比,选择了适宜的展开剂。

Using the binomial fitting method in MATLAB to program numerical calculation program, the analytical formulations between feed speed, width-radius ratio and width spreadratio were deduced.
