Feasibility Study of Implementing a Code Division Multiple Access Data Link Utilizing Fiber Optic Delay Lines.

摘要

This thesis investigated the feasibility of implementing a code division multiple access (CDMA) data link that employs fiber-optic delay-line signal processing. A two-user unidirectional data link was built and tested. A review was done of the various coding techniques and signals as used in spread spectrum systems. The thesis discusses hardware design and component selection from both an overall system structure to a more detailed component design. Results of the overall design effort show that a CDMA scheme employing fiberoptic delay lines provides a viable option for multiple access networks supporting high rates of data transfer. Additionally the lack of network synchronization between transmitter and receiver makes this particular scheme straightforward to implement. CDMA, Fiber Optics, Multiple Access, Spread Spectrum.
