A review on Estimation of Chromatic Dispersion using Fractional Fourier Transform in Optical Fiber Communication

Estimation of Chromatic Dispertion with FR. FT in Optical Cable

“…As shown in the Fig. 1 mutual complementary pair of the time signal and the transformed frequency signals respectively with the angle α which infers the CD or chirping signal to calculate the parameter p and can be refers to (2* α) / pi [1]. FrFT of a signal can be expressed with and defined as [2] The FrFT is special category of TF transform as that of Short Time Fourier pair.…”

“…In the trailing figure 1 it can be related the pair in the FT environment for the time and frequency. The rotation of the new time plan with reference to the new frequency can be expressed as the chirping angle α and the LFM parameter is the important data for obtaining the p of the signal can be equal to (2* α) / pi [1].…”

“…The equation 4can be used for finding the maximum value that resulted from the scanning for the optimum order, while setting the (4) to null, s(t) becomes an impulse response and that obtained hence p optimum of the system. Make chirping component set to zero order can call optimum order [1] = 0 (5)…”

“…Since order is (2* α) / pi =0 implies Here C is the LFM parameter and signal can be visualized with an AF [1] in the guided media. So the guided wave represented as following equation [2] = M. e t2 7So f(u)= dt 8If So order p can be (9) Then the order can be obtained as in (10) with subsisting in [9].…”

“…In [1] delineated various methods for the estimation of Dispersion using Fractional Fourier Transform. The implemented algorithm is the novice model which works efficiently in the independent of media and the modulation Techniques.…”
