Three novel designs of adaptively modulated optical orthogonal frequency division multiplexing modems using subcarrier modulation (AMOOFDM-SCM) are proposed, for the first time, each of which requires a single IFFT/FFT operation. These designs has a number of salient advantages including a significantly simplified modem configuration due to the involvement of a single IFFT/FFT operation, input/output...
Three novel designs of adaptively modulated optical orthogonal frequency division multiplexed modems using subcarrier modulation (AMOOFDM-SCM) are proposed, each of which is based on a single IFFT/FFT operation and offers input/output reconfigurability.
An adaptively modulated optical orthogonal frequency division multiplexing (AMOOFDM) modem using subcarrier modulation (SCM) (AMOOFDM-SCM) is proposed, for the first time, which consists of two conventional AMOOFDM modems in parallel with one operating at the baseband and the other being modulated onto an intermediate radio frequency (RF) carrier. Numerical simulations of the transmission performance...
