Exploiting Frequency Diversity on a Sub-band Basis for Optical Transmission Performance Enhancement

摘要

An optical data transmission method comprising partitioning an optical signal into a plurality of frequency sub-bands, generating a signal frequency mapping that rearranges the plurality of frequency sub-bands, choosing a plurality of frequency components based on the signal frequency mapping to form a set of frequency components, and transmitting the set of frequency components using frequency diversity transmission. An optical data receiving method comprising obtaining a signal frequency mapping for an original signal, receiving an optical signal that comprises a plurality of frequency sub-bands, re-arranging the plurality of frequency sub-bands using the signal frequency mapping to generate a restored original signal, and processing the restored original signal to recover an original data sequence.
