We present an efficient channel estimation method for coherent optical OFDM (CO-OFDM) based on intra-symbol frequency-domain averaging (ISFA), and systematically study its robustness against transm
Discrete multitone (DMT) uses an inverse discrete Fourier transform (IDFT) to modulate data on the carriers.
Nonlinear penalties due to intrachannel four-wave mixing (IFWM) in highly dispersed return-to-zero differential-phase-shift-keyed transmission are studied for both symmetric and nonsymmetric disper
Nonlinear penalties due to intrachannel four-wave mixing (IFWM) in highly dispersed return-to-zero differential-phase-shift- keyed (RZ-DPSK) transmission are studied for both symmetric and non-symm
Constraint-based routing gradually becomes an essential enabling mechanism for a variety of emerging network services such as virtual private networking and QoS support.
FPGA-based intradyne real-time receivers have received increasing attention because of ease of implementation.
Amorphous Tb-Fe thin films have been produced by dual-gun dc magnetron cosputtering, which allows a moderate range of compositions (spanning about 20 at.
The noise in the measurement of the resistance of a transition edge sensor slightly above the zero resistance state contains a noise component associated with fluctuations in the superconducting or
This paper proposes a new generic technique for fiber optic chemical sensing, discusses experiments which demonstrate the technique, and briefly treats possible extensions and applications.
The fractional quantum Hall effect is observed at low magnetic field where the cyclotron energy is smaller than the Coulomb interaction energy.
