Analysis of Bit Error Rate in Fast Optical-OFDM for Long Term Evaluation Networks

Abstract

A communication system has a capability of transferring the data from source to destination on this planet. There will be a rapid growth in communication technology due to the day by day enhancement in the number of subscribers. Thus the need of bandwidth has increased tremendously, but most of the networks were restricting the bandwidth allocation to certain limit, which in results degradation in the performance of the system there by its quite difficult to obtain high speed data transfer over the communication channel. These reasons motivate us to implement efficient bandwidth based data transmission schemes. In this article, we proposed an analysis of bit error rate in fast optical OFDM (FO-OFDM) systems for LTE up and down links. We utilized Bi-orthogonal wavelet decomposition (BoWD) to improve the spectral efficiency of the proposed system. Additionally, we also considered different channel distribution environments to demonstrate the robustness and effectiveness of our proposed approach. Extensive simulation results show that the proposed model performed superior over the state-of-art OFDM system such as Optical-DFT-OFDM.
