In this paper, different detection technique is presented through bit rate 1Gbps. Advanced modulation technique is used for enhancing the performance of optical access network. Differential phase shift keying (DPSK) has significant attention for the researcher during last two decades. Optisystem version 12 has been employ for investigate the transmission capability of the hybrid system. The comparison...
This paper develops new coding technique to generate multiplexed patterns for Duty-Cycle Division Multiplexing (DCDM) which allows users to share the single transmission medium by assigning different duty cycles for each user. This coding technique aims to reduce the amount of noise which is added due to multilevel signalling. Single channel back-to-back optical fibre system is designed based on the...
This research work focuses to design Hybrid OCDMA over WDM system with advance modulation techniques DPSK which will improve the performance for long distance fiber length. Hybrid system merges with different types of techniques like OCDMA and WDM. Modified double weight (MDW) code is proposed as the signature address code. Multiuser interference and increase the bit-error-rate might be condense satisfactory...
