Summary:
In this paper, we propose a model of optical codedivision multiple access (OCDMA) system using the light-emitting diode (LED) as an optical source and the avalanche photodiode (APD) as a light-receiving element. In addition, we compare the bit-error rate (BER) performance using the proposed model with that obtained by transmission experiments of the OCDMA system using the optical zero-correlation zone (ZCZ) sequence whose correlation property is completely orthogonal in a zone around shift 0 in order to evaluate the effectiveness of the proposed model. As a result, their BER performances are nearly equal, and it is clarified that the proposed model is well modeled on the actual system.
