In digital communications, as an alternative to conventional time domain equalization (TEQ), frequency domain equalization (FEQ) has been of interest, in particular for OFDM. In any optical channels, such as in fiber optic transmission or free-space optical communications (FSO), there can be channel dispersion, causing intersymbol interference (ISI). One feasible solution to this is FEQ of the distorted light signal by established theory of equalization. A new idea is presented that examines possibility of adaptive optical frequency-domain pulse shaping and equalization to remedy the optical channel dispersion problem in the light spectral domain.
