Young, "All-optical CDMA with bipolar codes," <i>IEEE Electronic Letters,</i> vol. 31, 1995.https://hdl.handle.net/1911/20151Journal PaperA method for the transmission and detection of bipolar sequences in a unipolar system is presented. It allows all-optical implementation, in noncoherent optical CDMA systems, of the bipolar codes that have been developed for the radio domain. A practical design is described that encodes the spectrum of a broadband optical source to support a large number of subscribers.engcode division multiple access (CDMA)optical communicationsJournal articlecode division multiple access (CDMA)optical communications
