Code Division Multiple Access Local Area Network Communications Employing Fiber Optic Signal Processing Techniques

Abstract

This thesis investigated the feasibility of implementing a code- division multiple-access (CDMA) local area network (LAN) employing all-optical signal processing. A two-user unidirectional data link was built and successfully tested. This data link utilized variations of optical orthogonal code sequences (OOCs) generated by serially connected fiber optic delay lines and 2x2 couplers. A special feature of this network design was use of the same hardware to decode the signal as was used to encode the signal. A detailed review of the various coding techniques and the generation of spread spectrum signals was also performed. The results of the overall system design effort demonstrated that high-data-rate signal traffic can be supported by the network and in a more power efficient and affordable manner than previous designs.
