CODE GENERATION PARADIGMS ON OPTICAL ORTHOGONAL AND OTHER CODES IN A FIBER OPTIC CDMA LAN

Code Division Multiple Access (CDMA) techniques, by far, had been appl ied to LAN problems by many investigators, An analytical study of well known algorithms for generation of Orthogonal codes used in FO-CDMA s ystems like those for prime, quasi-Prime, Optical Orthogonal and Matri x codes has been presented, Algorithms for OOCs like Greedy/Modified G reedy/Accelerated Greedy algorithms are implemented. Many speed-up enh ancements. for these algorithms are suggested. A novel Synthetic Algor ithm based on Difference Sets (SADS) is also proposed. Investigations are made to vectorise/parallelise SADS to implement the source code on parallel machines. A new matrix for code families of OOCs with differ ent seed code-words but having the same (n,w,lambda) set is formulated .
