We demonstrate by simulation that the superimposed training based channel estimation scheme can achieve similar performance as compared with conventional schemes, without any loss in bandwidth. An ite...
We demonstrate monitoring of digitally-generated laser linewidths for 107-Gb/s coherent optical OFDM systems. Unique characteristics of time-domain phase-error variance are exploited to extract laser ...
We demonstrate application of polarization-switched-QPSK subcarrier modulation together with soft-FEC LDPC coding and iterative demapping on OFDM lab system. 4.5dB OSNR-sensitivity improvement versus ...
The timing and optical laser phase of individual bands in multi-band OFDM are correlated. We significantly reduce the OFDM overhead through using FFT window synchronization for channel estimation and ...
We propose DFT-spread (DFT-S) OFDM within each sub-band of multiband-CO-OFDM to mitigate fiber nonlinearity. For 1000-km standard-single-mode-fiber transmission at 420-Gb/s, 32-band DFT-S CO-OFDM outp...
The impact of PMD on wavelet transform based optical OFDM (WTO-OFDM) systems is investigated. Simulations show that WTO-OFDM is very sensitive to PMD. A 1-dB penalty at 5-ps DGD is incurred for 112-Gb...
Simulations show that by pre-compensating for dispersion, using bands transmitted with timing offsets and a single-band receiver, the cyclic prefix to be reduced in optical OFDM systems without compro...
We consider Active Constellation Extension to reduce the PAPR in CO-OFDM systems. We find that the nonlinearity threshold is improved by 1.5 dB at a reach of 400 km SSMF fiber.
We extended a pilot symbol frequency offset estimation scheme and applied it in combination with a pilot subcarrier compensator. Optimum system sensitivity was found up to few 100MHz frequency offset.
