| Popis: | The dramatic increase in demand for services that require high bandwidth and augmented bitrate to function properly has become a trend in recent years. In order to comply with the current demand, telecom companies struggle to enlarge the offered capacity as well as to minimize the latency and to enhance the reliability of the network. An effective technique to increase the capacity is to move to higher frequency bands, such as millimeter wave band, where the inherent features promise larger capacities and less interference. The other proven method to increase the capacity is to incorporate optical coding in conjunction with the guidelines of optical code division multiple access (OCDMA) where the number of users is increased based on the assignment of optical orthogonal codes to every user. Finally, through the application of multiple wavelengths to transmit optical encoded signals in multiple channels, as suggested by the wavelength division multiplexing (WDM) scheme, the capacity can be increased substantially. In this paper, a W-band WDM-over-OCDMA system is presented. The simulation results show the effect of various optical codes, profiled in a superstructure fiber Bragg grating (SSFBG) device as encoder/decoder, and wavelength channels on the BER versus the received optical power. |
