Abstract :
We analyze, for the first time, the performance of a simple serial-search algorithm for optical code-division multiple access (CDMA) systems using optical orthogonal codes (OOC). For our analysis, we use advanced photon-counting methods and we consider the effect of shot noise and dark current and multi-access interference. We use two approaches for considering the effect of multi-access interference on the performance of the synchronization system. One approach is the general method of considering the average effect of interference. In the other approach, we introduce a new concept for modeling interference; then, with the help of this model, we obtain results that can be regarded as upper and lower bounds on the performance of the synchronization system
