Proposal of ICI cancellation using opposite weightings on symmetric subcarrier pairs in CO-OFDM systems
ICI cancellation using opposite weighting on symmetric subcarrier pairs. Improvement of phase noise tolerance of laser source. SNR improvement in nonlinear transmission region. Software redefinition without hardware changing compared with conventional OFDM. A software based adaptive scheme.
