Abstract

Full Duplex 64-QAM OFDM MIMO is used for transmitting the signal in uplink and downlink direction simultaneously. The performance and simulation of the system is done by RF carrier frequency at the W-band that enables the convergence between optical fiber and wireless system for access networking. The proposed system is based on WDM, PDM and 64-QAM OFDM techniques. The system is highly efficient with low latency and bit error rate. The system efficiency could be achieved by BER, Q-factor and eye height.

Introduction

Upcoming generation facing plethora of hurdlers related to high speed and data rates. Moreover, there is worldwide plunge in mobile data trafficking with 4k folds over past 10 years and is estimated that it may increase 7 folds between 2019 and 2025. Many scholars approached to distinct techniques such as resilient spectrum management, mm-wave technique and many more to meet all these challenges. A promising solution to fulfill all such demands is Fiber wireless system as in this it provides flexible access network in dense small cell networks. Fi-Wi system has been proposed due to low latency, flexibility and low data rate transmission of signal. In such system, analog system is directly transmitted through the fiber and wireless channel without converting to the digital form. Full Duplex MIMO system is useful in 5G networks as Full Duplex system reduces the self interference and cross talks so that signal is send and received in resilient manner. Combination of Full Duplex with MIMO proved to be fruitful as it surged the capacity of data, secure, robust and also reduced the errors occurring during the transmission and reception of the signal .
