Analysis of the error probability for optical unipolar two-dimensional codes using a serial elimination interferences receiver

Abstract

The utilization of unipolar optical two-dimensional codes(2D codes) employed in OCDMA systems has given a better system performance and a diminution of multiple access interferences (MAI) relative to optical unipolar codes with one dimension(lD code). In this paper we study the error probability of 2D optical codes namely prime hop system and hybrid codes using a probability distribution approach. We demonstrate in this work that we have a higher performance when we use serials eliminations interferences receiver versus conventional receiver, in other words the error probability is decrease and the system provide an important number of simultaneous users sharing the network.
