中文说明：应用背景滤波器组的多载波（FBMC）传输技术导致一个增强的物理传统的通信网络层，它是一个有利的技术为新概念和，特别是，认知无线电。本文件的目的是提供FBMC的概述，重点对的特点，影响通信网络。唯一的前提阅读文件是数字信号处理的基本知识，特别是抽样理论，快傅里叶变换（FFT）和有限脉冲响应（FIR）滤波器。更彻底在所描述的技术的发展，以及替代性和更复杂的方法。关键技术演讲开始与FFT载波的直接应用通信，指出这种简单的方法，限制和，特别是，的频谱泄漏。然后，它表明FFT方法可以进化到一个滤波器方法是简单的设计与实现。每个数据块的时间，窗口扩展到多载波符号周期和符号重叠在时间域。这是在传统的有效时间重叠的单载波的基础上调制解调器在符号间干扰避免如果信道滤波器满足Nyquist判据。这一基本原则适用于多载波传输。关于实施，滤波器组的方法是一个扩展的直接FFT方法和可扩展的FFT实现。 ；
English Description：
Application backgroundThe filter bank multicarrier (FBMC) transmission technique leads to an enhanced physical layer for conventional communication networks and it is an enabling technology for the new concepts and, particularly, cognitive radio. The objective of this document is to provide an overview of FBMC, with emphasis on the features which impact communication networks. The only prerequisite for reading the document is basic knowledge in digital signal processing, in particular sampling theory, fast Fourier transform (FFT) and finite impulse response (FIR) filtering. More thorough developments on the techniques described, as well as alternative and more sophisticated methods.Key TechnologyThe presentation begins with the direct application of the FFT to multicarrier communications, pointing out the limitations of this simplistic approach, and, particularly, the spectrum leakage. Then, it is shown that the FFT approach can evol
