Characterization and Monitoring of Laser Linewidths in Coherent Optical OFDM Systems
Fiber optics communications Modulation
2011/5/26
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 ...
Reducing Cyclic Prefix Overhead in Optical OFDM Systems
Reducing Cyclic Prefix Overhead Optical OFDM Systems
2009/7/14
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...
