The overhead of cyclic prefix (CP) in coherent optical OFDM (CO-OFDM) tends to be too large for high-speed and long-haul optical fiber transmissions. We discuss and experimentally demonstrate a transmission of reduced guard interval OFDM (RGI-OFDM) with much reduced CP overhead based on digital sub-band demultiplexing. The proposed techniques are used to(More)
