Coherent OFDM-PON Downstream Transmission with Dispersion Compensation

Problem Definition

PROBLEM DESCRIPTION: Despite the advancements in OFDM-PON communication systems using m-QAM mapping, the downstream transmission still faces challenges related to data rate efficiency, subcarrier utilization, and channel capacity. These issues hinder the overall performance of the system and limit its capability to meet the increasing demand for high-speed data transmission. Current systems are not able to fully utilize the available spectrum and are unable to achieve the desired data rates in an efficient manner. In order to address these challenges, a novel approach is required to enhance the downstream transmission in OFDM-PON systems. The proposed project aims to design a dispersion compensated model for coherent detection in OFDM-PON downstream transmission.

By introducing the concept of dispersion compensation, the project seeks to improve the system's performance in terms of data rate, subcarrier utilization, and channel capacity. The research will focus on developing a model that optimizes the use of subcarriers in CO-OFDM for downstream transmission, ultimately increasing the efficiency and capacity of the system. By overcoming the limitations of current systems, the project aims to provide a solution that can meet the growing demands for high-speed data transmission in a more effective manner.

Proposed Work

The research work titled "A dispersion compensated model design for coherent detection in OFDM-PON downstream transmission" focuses on improving the performance of coherent optical OFDM (CO-OFDM) systems for long haul transmission, specifically in the downstream transmission. Previous OFDM-PON communication systems using m-QAM mapping have been found to be less efficient in terms of data rate, subcarriers, and channel capacity. In this proposed work, a novel approach is introduced to address these issues, incorporating the concept of dispersion compensation. By analyzing the system's performance at the highest data rate, the research aims to enhance the efficiency of OFDM-PON systems for improved downstream transmission.
