Ravindra Nagar, Gurjit Kaur . Simulation and Performance Analysis of 2-D Codes at 1 Gbps and 1.25 Gbps Data Rate for OCDMA LAN Applications. International Journal of Computer Applications. 49, 8 ( July 2012), 42-48. DOI=10.5120/7650-0744
Abstract
Two main forces behind a lot of interest in the OCDMA techniques are the ability to support asynchronous, bursty data transmission and data access security. To achieve high speed connectivity with a large bandwidth, OCDMA is a highly flexible technique. This paper describes a simulated system for an incoherent OCDMA system using high performance 2-D codes. In this paper we have designed an OCDMA system for 1 Gbps and 1. 25 Gbps using (8×4) wavelength hopped-time spreaded 2-D optical codes. The analysis takes into account the effect of data rate for increasing number of users at different length of fibers. The system performance is evaluated by Q-Factor analysis and timing diagram at different data rates i. e. 1 Gbps and 1. 25 Gbps Results show that the designed system provides adequate BER (10-9) for 1 Gbps up to 10 users.
