SSFBG Based Decorrelator for Synchronous Optical CDMA Systems

Research output: Contribution to journalArticlepeer-review


A Superstructured Fiber Bragg Grating (SSFBG) based decorrelator for removing Multiuser Interference (MUI) in a synchronous Optical Code Division Multiple Access (OCDMA) system is reported. Theoretical investigations reported in this work demonstrate that it is possible to ‘wipe-off' MUI almost totally at the sampling instants by using a SSFBG whose superstructure is derived from the correlation matrix of the spreading sequences used by the transmitters. Though for demonstration of the results we have considered a simple Modified Prime Sequence (MPS) set of cardinality four derived from GF(2), the ideas presented in this work should be easily extensible to synchronous OCDMA systems employing spreading sequences of larger cardinality and supporting more number of users.
