Is there any code available which i can study ! where signal is reconstructed in frequency domain using Least sqaure...Like one of file submisson was Fast gridding method.....they calculate the frequency domain spectrum or i should say that they calculated A^(H)WY (which is dft with weights) now i want to apply least square on this ..fr reconstruction so that i can apply ifft and get back my signal..

Sir, 
Even i can get the Fourier domain spectrum by Taylor approximation.....after that i need to work on it...........question is how

Hey greg! Its not a signal reconstruction, its the same grid on which we are getting a signal
