High Spectral Efficiency OFDM Based on Complex Wavelet Packets
We propose a novel type of CO-OFDM based on the recently developed dual-tree complex WPT (DT-CWPT). In particular, polarization mode dispersion (PMD) can be compensated by digital signal processing using a DT-CWPT which is characterized by a single-side band. Numerical simulations show that the 1 Tb/s single-channel CO-OFDM transmission over the distance of 1800 km with the spectral efficiency (SE) of 7.88 bit/s/Hz can be realized.
