Abstract

User spread is recent technique which is applied in optical IDMA (O-IDMA) to achieve the high rate transmission with zero dispersion fiber. User spread optical interleave division multiple access is a multiple access scheme which has less inter symbol interference (ISI) and multiple access interference (MAI) as compared to conventional CDMA. US-OIDMA is the combination of CDMA and IDMA. The efficient bandwidth utilization is one of the key aspects for improving the performance of optical fiber based communication system. Therefore US-OIDMA is used in optical fiber mode for high speed transmission with zero dispersion fiber. The performance of US-OIDMA has been evaluated and compared with OIDMA using MATLAB software. It is concluded that US-OIDMA is far better than OIDMA and support more number of users and less bit error rate.
