A FBMC based ISDB-Tb Digital TV Frame Proposal

Abstract

Nowadays, one of the challenges of communications systems is to enhance spectrum utilization and data rate without robustness loses. This situation is more perceptive in digital television applications, since there is a constant need of providing better experiences to the users with the transmission of higher resolution videos. In this context, novel approaches for the physical layer of such systems are subject of intense research, including investigation on the effect of replacing the Orthogonal Frequency Division Multiplexing (OFDM) technique currently used by other modulation schemes such as Filter Bank Multi Carrier (FBMC). This article presents a novel FBMC based frame implementation for the Integrated Services Digital Broadcasting Terrestrial Version B (ISDB-TB), developed as a software defined radio (SDR). The results show the robustness and rate gains of FBMC and prove that ISDB-TB frame can be modified to enhance the performance in Digital TV applications.
