The dynamic input power range resulting in BER<;10-3 using our proposed joint-SPM compensation scheme can be increased by 0.4 dB and 1.2 dB, compared to separately compensate for SPM at either transmitter or receiver side.
In this paper, we propose, analyze, and experimentally verify polarization-multiplexed optical wireless transmission with coherent detection as a means of improving performance and increasing the per-wavelength data rate in the presence of atmospheric turbulence. It is first shown that in terrestrial last-mile applications, the polarization state changes of the optical wireless signal are governed...
We experimentally demonstrate a novel decision-aided maximum likelihood phase estimation in an 8-Channel 42.8-Gbit/s DWDM coherent PolMux QPSK system. The results show that our proposed algorithm can achieve a comparable performance as the Mth-power while having much lower computational complexity.
We propose and experimentally demonstrate a novel, dual-stage frequency offset estimator and achieve the widest range of ?? 0.5 times the system symbol rate for the first time in a 42.8-Gbit/s coherent PolMux QPSK receiver.
We report a novel design for high-speed all-optical OFDM employing coupler interferometry for IFFT/FFT. 160-Gb/s DQPSK transmission using eight sub-carriers was simulated, while 25-Gb/s DPSK experiment using two sub-carriers was performed using matched delay interferometers.
