function recon = FourierDeNoise(y)
% FourierDeNoise -- Hard thresholding in Fourier Domain
%  Usage
%    recon = FourierDeNoise(y)
%  Inputs
%    y        1-d complex valued signal; 
%             noise should be complex-valued white noise
%  Outputs
%    recon    reconstruction after sqrt(2 log(n)) thresholding
%
	n = length(y);
	fy = fft(y);
	af = abs(fy);
	ty = af > (sqrt(2 * log(n)) .* sqrt(n));
	cy = fy .* ty;
	recon = ifft(cy);
