with a length of 231–1.Figure 8b and dcompares the spectral measurements (for on-off keying and binary phase-shift keying modulation, respectively) with the spectrum resulting from the simulations convolved with the spectral response of the OSA (a resolution filter with 0.01 nm bandwidth)....
Assuming an ideal rectangular modulation window equal to the pulse repetition period T ¼ 1/Df, the frequency comb will be convolved with a sinc function in the frequency domain9 having zero crossings at n Á 1/T ¼ n Á Df, with n being a non-zero integer number. Thus, the ...
The second algorithm uses the convolution of covariance of fractional Gaussian fields with the fractional differential Heaviside function, which is the limit of FS. In the proposed algorithms, the given noisy image is processed in a blockwise manner. Each processed pixel is convolved with the mask ...
