摘要

当前通信系统面临的挑战之一是如何在不损失鲁棒性的前提下提高频谱利用率和数据速率。这种情况在数字电视应用中更为明显，因为不断需要通过传输更高分辨率的视频为用户提供更好的体验。在这种背景下，这种系统的物理层的新方法是激烈研究的主题，包括研究替代正交频分复用(OFDM)技术的影响，目前使用的其他调制方案，如滤波器组多载波(FBMC)。本文提出了一种新的基于FBMC的综合业务数字广播地面版B (ISDB-TB)的帧实现，作为软件定义无线电(SDR)开发。结果表明了FBMC的鲁棒性和速率增益，并证明了ISDB-TB帧可以通过修改来提高数字电视应用中的性能。

A FBMC based ISDB-Tb Digital TV Frame Proposal

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.
