Abstract

The efficient bandwidth utilization is one of the key aspects for improving the accomplishment of any optical fiber based communication system. Code-Division Multiple- Assess (CDMA) scheme has been popularly deployed, in optical platform, for attaining the higher spectrum efficiency throughout the globe. However, the entire Optical CDMA (O-CDMA) scheme based communication systems have been victim of increased multiple access interference (MAI) with increment in user count. Recently, Interleave-Division Multiple-Access (IDMA) scheme has attracted the researchers for working on its feasibility with optical communication. From the literature, it has been revealed that IDMA scheme, which employs interleavers as the only means for user separation, mitigates efficiently with MAI and other interferences. In this paper, the performance of Optical Interleave Division Multiple Access (O-IDMA) based system has been evaluated using low rate convolution codes. During the simulation, the combination of coding and spreading operations has been employed for maximizing the coding gain using low rate codes. The simulation results establishes that with low rate convolution encoding technique, O-IDMA system contributes significant refinement in system performance in comparison to its counterpart i.e. O-CDMA system.
