Abstract :
The effect of both shot noise and thermal noise on the performance of the optical code-division multiple- access (OCDMA) round robin receiver/transmitter (R3T) protocol is examined. Several performance measures, namely, the steady state system throughput, the protocol efficiency, and the average packet delay are evaluated. Our results reveal that the R3T is immune against both thermal and shot noise. We found out that there are optimum values for the laser power to compensate for this degradation.
