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