I seem to be unable to duplicate the results of the following paper, in making the window function spectrum match what the author presents. (Md Abdus Samad, “A novel window function yielding suppressed mainlobe width and minimum sidelobe peak,” International Journal of Computer Science, Engineering and Information Technology (IJCSEIT), Vol.2, No.2, pp. 91-103, April 2012.) I have not been able to elicit a response from the author. Has anybody made this window work? If so, do you have a Matlab snippet that implements it?
I changed the third item in equation (4) to 0.0007339M. It gets closer (but not exactly) to the results described in the paper.
When the mainlobe gets wider, the sidelobe is lower, and vice versa. Various window functions in Matlab toolbox can be chosen to meet many practical demands, otherwise, some optimization methods can be used to customize the frequency response.
