Design & Implementation of Optical Codes in Multiusers WCDMA Network

Wideband Code Division Multiple Access (WCDMA) merges the large bandwidth of the optical fiber with the flexibility of the CDMA technique to achieve high speed connectivity. This paper presents the designing of optical codes for multiuser WCDMA network. The proposed network permits large number of users to communicate at elevated data rate. This paper demonstrates a technology for an incoherent optical code-division multiple-access scheme based on wavelength/time codes. The designed codes supports multiusers operating at 10 Gsymbols/s/user while maintaining the proper bit-error rate (BER) for the correctly decoded signal.
