Optical CDMA Network Performance in Presence of Impairments

The performance of optical code division multiple access (CDMA) network is severely degraded by the optical multiple access interference (OMAI) from other active users. This limits the number of active users simultaneously accessing the network. In this paper, various methods to reduce OMAI has been reviewed. The paper also reviews the performance of the optical CDMA network in presence of OMAI, receiver noise, thermal noise, shot noise and other impairments
