In this paper we illustrate a procedure to evaluate the optimum receiver threshold in Optical Code Division Multiplexing (OCDM) systems using Gold Codes. The use of the optimum threshold allows for a higher number of optical codes carried on each wavelength. The increase in OCDM/WDM Optical Packet Switch performance is also evaluated when the threshold optimization is performed. We show that when the offered traffic is equal to p=0,7, the packet loss probability of the OCDM/WDM switch in saturation conditions, equals 1, 28*10(-6) in the case in which the optimal receiver threshold is used. On the contrary the performance reaches only 3, 91*10(-4) if a traditional threshold is chosen.

Abstract
In this paper we illustrate a procedure to evaluate the optimum receiver threshold in Optical Code Division Multiplexing (OCDM) systems using Gold Codes. The use of the optimum threshold allows for a higher number of optical codes carried on each wavelength. The increase in OCDM/WDM Optical Packet Switch performance is also evaluated when the threshold optimization is performed. We show that when the offered traffic is equal to p=0,7, the packet loss probability of the OCDM/WDM switch in saturation conditions, equals 1, 28*10(-6) in the case in which the optimal receiver threshold is used. On the contrary the performance reaches only 3, 91*10(-4) if a traditional threshold is chosen.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
