Optical CDMA is a technique based on the same principle of CDMA, in which each individual user is assigned by a unique code. OCDMA consists of distributing the power of the transmitted signal across an enormously wider bandwidth which is necessary to transmit the information. In fact, OCDMA offers a significant role in optical fiber communication due to several attractive characteristics such as dynamic bandwidth assignment, high security, low cost, low interference, and flexible quality. On the other hand, WDMA is a technique that provides a division of the optical channel into subchannels. In this paper, an investigation of the performance of a hybrid WDMA-OCDMA system based on Laguerre Gaussian modes has been illustrated. The analysis is done by using 2D ZCC/MD code according to its success demonstrated in various investigations. 2D ZCC/MD code is distinguished by a property of zero cross-correlation which affords a capability in order to reduce receiver noise and Multiple Access Interference (MAI). In addition, 2D ZCC/MD code proved an ability to improve the system performance in terms of cardinality and other factors that can affect the system. The transmission is done over multi-mode fiber (MMF) which can be applied in a short haul-local area network. Furthermore, the system is implemented based on Three different Laguerre Gaussian modes (LG 01, LG 02, and LG 03). The evaluation of the system performance is done based on Bit Error Rate (BER), Q-Factor, and eye diagrams measurement. [ABSTRACT FROM AUTHOR] |
