A serial coding method which combines D-ary wavelength-shift keying (WSK) with incoherent CDMA and a parallel coding method, where the channels are distinguished by time/wavelength-matrices, are investigated. We analyze the theoretical performance and show numerical results for different code families.enchannel codingcode division multiple accessmatrix algebraoptical communicationoptical linksoptical modulationtime/wavelength codingdiffuse infrared communication systemsmultiple optical carriersmowcdmaasynchronous accessdiffuse ir-systemsserial codingd-ary wavelength-shift keyingwskparallel codingtime/wavelength-matrices621conference paper
