Abstract
We propose two possibilities to combine multiple optical wavelengths (MOW) with code division multiple access (CDMA) to achieve asynchronous access in diffuse IR-systems. 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.
