One Design of Pseudo Pilot to Suppress the Nonlinear Interference in Optical OFDM/OQAM System

Orthogonal frequency-division multiplexing offsetquadrature amplitude modulation (OFDM/OQAM) system relaxes the orthogonal condition of the sub-carriers from the complexed domain to the real field. With the improve of transmission efficiency, it also greatly increases the interference of nonlinear effect. In this paper, we design the Pseudo Pilot according to the nonlinear transmission model established before, which can immensely promote the tolerance of optical OFDM/OQAM system to nonlinear interference.
