We propose an algorithm for CO-OFDM receivers to perform overlapped frequency-domain CD and PMD equalization before OFDM symbol demodulation. This approach enables OFDM transmission with a small cycli...
Novel robust digital carrier phase/frequency recovery structure is experimentally demonstrated for single carrier and multi-carrier, up to 40Gb/s, photonic-wireless links in 75-110 GHz band. We show t...
Dispersion compensation fiber is one of the causes of transmission delay in optical systems. We demonstrate a low-latency model system employing electronic pre-equalization. The pre-equalization techn...
We propose and demonstrate using signal pre-distortion and equalization schemes for increasing the data rate of the white-light LED communication system. Bit-error-rate of <10 -10 at 10-Mb/s operation...
For chip-design of a frequency-domain equalizer, a simple procedure to minimize the number of multiplications is shown. Considerations include recent improvements of FFT-algorithms.
We demonstrate digital equalization of 40Gbps data enabled by use of Real-time Burst Sampling (RBS) with photonic time-stretch A/D converter. Evaluation of a feed-forward equalizer and a decision feed...
W e propose a coherent detection scheme with one sample per symbol. MLSE is used to compensate for ISI introduced by anti aliasing filtering. 50,000 ps/nm of CD is fully compensated with only 1 dB pen...
PolMux increases PMD sensitivity compared to single polarization transmission. We investigate the equalization of first and second order PMD in the optical domain and determine the respective remainin...
Semi-blind sequence is proposed for optimizing the nonlinear equalization parameters from limited prior knowledge of link. Its performance is demonstrated in an extreme case where the fiber type of a ...
We experimentally investigated transmission performance of 16QAM-OFDM signal over 25-km fiber and 5-m air distance using 60GHz ROF technology. It is the first time that the details of optimal equaliza...
The application of electronic distortion equalization (EDE) for Apol-RZ-DPSK has been evaluated experimentally and numerically. EDE extends the DGD tolerance by ~30%, if the polarization will be contr...
We demonstrated 25-Gb/s (21.7-Gb/s after coding) single-carrier (SC) transmission with QPSK format over 240km of SMF (4080ps/nm) by employing frequency-domain equalization (FDE).
