Abstract
Presents a resume of the work on the application of CDMA techniques in optical fibre LANs. The work carried out shows how direct-sequence baseband spread-spectrum techniques, using sequence inversion keying (SIK) of unipolar code sequences, may be applied to the CDMA protocol for an optical fibre LAN. A mathematical model of the optical CDMA system is presented and used to derive performance measures for the system. A new algorithm for choosing suitable sets of code sequences is presented and a new class of code sequences for use with an optimum matched filter detector in a CDMA system is described
