  We investigate the Generalized Parton Distributions(GPDs) of proton by
expressing them in terms of overlaps of light front wave functions (LFWFs)
using a simulated model which is able to qualitatively improve the convergence
near the end points of $x$. We study the spin non-flip $H(x, \zeta, t)$ and
spin flip $E(x, \zeta, t)$ part of GPDs for the particle conserving $n
\rightarrow n$ overlap in the DGLAP region $(\zeta<x<1)$. The Fourier transform
(FT) of the GPDs w.r.t. to the transverse momentum transfer as well the FT of
the GPDs w.r.t. $\zeta$ have also been obtained giving the distribution of
partons in the transverse position space and the distribution in the
longitudinal position space respectively. Diffraction pattern is obtained for
both $ \mathcal{H}(x,\sigma,t)$ and $ \mathcal{E}(x,\sigma,t)$ in the
longitudinal position space.
