Applying implicit training to polarization-division-multiplexed coherent optical systems

open access: goldOptics Express, 2013
We report the use of implicit training-aided channel estimation (ITA-CE) for polarization-division-multiplexed (PDM) single-carrier coherent optical systems. With the concept of ITA-CE, where the training sequence (TS) is arithmetically added onto the information symbols rather than appearing in separate time slots, overhead-free transmission can be ...

Absolute polar duty cycle division multiplexing over wavelength division multiplexing system [PDF]

open access: yesOptics Communications, 2009
The performance of absolute polar duty cycle division multiplexing (AP-DCDM) over wavelength division multiplexing (WDM) system is presented based on the simulation results. The AP-DCDM signal has narrower bandwidth than conventional time division multiplexing (TDM) signal, which makes its implementation in WDM system advantageous.
