Abstract

In order to improve precision of classical spectrum correction because of traditional window function's restricting,new window recreated method on convolution calculates is given.It has better ability by taking rectangular window for example in the same length.A new interpolation algorithm based on least square approximation is brought forth.The result shows this new algorithm can accomplish high-accuracy frequency survey but also has better project value.
