Patent ID: 8867931

Claim:
A communication system, comprising: an optoelectronic receiver configured to receive an optic signal conveyed from an electrooptic transmitter to an optic communication medium, comprising an analog domain representation of a radio frequency signal having frequencies above 698 MHz modulating the optic signal, and to produce an electrical analog domain signal corresponding to radio frequency signal frequencies above 698 MHz, including at least one intermodulation distortion product of the radio frequency signal; a digitizer configured to quantize the electrical analog domain signal to a digital stream having a sampling rate of at least 1.4 gigasamples per second; and a digital signal processor configured receive the digital stream and digitally reduce a representation of an amplitude of at least one intermodulation distortion product, dependent on a model of the intermodulation distortion properties of the at least one of the optoelectronic receiver and the electrooptic transmitter, and to produce a processed signal output.
