ABSTRACT:
A method and system for improving the linearity of an analog transmission in a multichannel fiber optic transmission system uses a power series correction derived from a non-information bearing portion of a received transmission. A notch filter reduces the energy in a portion of a guard band between channels before transmission so that the energy in the notch-filtered portion of the received transmission is indicative of the non-linearities introduced by the analog transmission system. The energy of the notch-filtered portion of a received transmission is represented by a power series that is inverted and provided as a correction to the received transmission.
