Resumo
This work aims to address and evaluate the performance of data transmission of an image
using the Orthogonal Frequency Division Multiplexing (OFDM) technology compared to the
Filtered Orthogonal Frequency Division Multiplexing (F-OFDM) technology. The F-OFDM is a
candidate technology to be used in the new generation of wireless mobile communication, the 5G.
In 5G, there is the prospect that high-speed services and availability will be offered to users, such
as: low-latency in mobile Internet, telemedicine, communication among devices such as machines
and vehicles (D2D - Device to Device) and paradigm of the Internet of Things (IoT - Internet of
Things). F-OFDM retains the advantages of OFDM and reduces important disadvantages by using
a filter design that smoothes truncation at the ends of its subbands, reducing OOBE (Out Of Band
Emission). In this work we also explore how the preparation for the transmission of an image
through an OFDM tecnology based network takes place and how it is retrieved at its destination.
Finally, simulation results of the transmission of an image through the channels of an OFDM and
F-OFDM network are presented and the transmission and reception processes are evaluated using
the following performance parameters: BER (Bit Error Ratio), PAPR (Peak to-Average Power
Ratio), Power Spectral Density (PSD) analysis in passing bandwidth, impact changes in filter
design, and a simplified way of verifying extra band emission (OOBE).
