A REVIEW BASED ON CHANNEL ESTIMATION FOR OPTICAL - ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING
Journal Title: International Journal of Electrical Engineering & Technology (IJEET) - Year 2019, Vol 10, Issue 2
Abstract
Optical - Orthogonal Frequency Division Multiplexing (OFDM) system generally employ in several communication devices such as telephone, radio, television, internet and so on. In the present days, the optical OFDM is one of the significant methods for an effective communication system. In communication technique, the channel estimation plays a major role in finding the characteristics of the channel based on the received data value. In order to manage the communication data, most of the researchers focused on the channel estimation by using different techniques like Minimum Mean Square (MMSE), Least Square, blind, semi-blind and also developed new methodologies in the coherent optical OFDM. This review paper analysed the research works based on the channel estimation algorithms of an optical OFDM and also examined the major limitation of these techniques. This paper will help the researchers to give a better solution for the present drawbacks in the coherent optical OFDM system.
