—Coherent Optical Orthogonal Frequency Division Multiplexing (CO-OFDM) finds a number of applications in the Telecommunication world. Though CO-OFDM is immune to the dispersive effect of the fiber channel it is subjective to the channel induced nonlinear effects. In our paper, we discuss the techniques to mitigate the intensity dependent nonlinear self –phase modulation (SPM) effects. Its highly important to reduce the phase shift introduced by the SPM since it results in added pulse broadening effect which remains uncompensated with the addition of cyclic prefix-suffix and the dispersion compensation schmes. A combination of Low Density –Parity Check(LDPC) codes with Volterra and Wiener-Hammerstein Electrical Equalizers are proposed to mitigate the SPM effect.
