Titel
Time/wavelength coding for diffuse infrared communication systems with multiple optical carriers
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.
