Abstract

This paper investigates the signal-to-interference ratio (SIR) performance of a single chip rate variable processing gain optical fast frequency hopping CDMA (OFFH-CDMA) system, using direct detection. A fiber-optic CDMA communication network is considered. A system model that allows multirate transmission is presented. In addition, the SIR is derived. A comparison between the exact value of the SIR and the approximation one assuming random sequences is also discussed.
