Analysis of OCDMA system performance based on QPSK modulation format for local area network

Abstract

The demand for higher communication and network communication system is the main reason for the need improvement of communication system to reach and meet the needs of customers. With the modern communication system allows all users to access with use of a simple and fast access. So, there is a high demand of design OCDMA system which will produce better signal quality. Therefore, in this project, a technique quadrature phase-shift modulation was tested with an optical code division multiple access code to analyze the performance of the system. In order to validate the performance of Modified Double Weight (MDW) is use as a signature code. Finally, the proposed system is applied for local area network (LAN) application to fulfill the users demand.
