Abstract.  An iterative algorithm is proposed and investigated for phase noise estimation of discrete Fourier transform spread (DFT-S) orthogonal frequency division multiplexing (OFDM). Compared with common phase estimation (CPE), significant improvement of tolerance to laser bandwidth is obtained and 2.7 dB improvement at BER of 3.8×103 is found using the CPE-iter scheme in 103.3  Gb/s coherent polarization-division-multiplexed DFT-S OFDM system over 480-km transmission through simulation.
