摘要

OFDM是一种将高速率数据流分成多个低速率数据流的多载波调制技术。使用相互正交的子载波调制低速率数据流。正交性使得多个子载波可以在狭窄的频率空间内同时传输而互不干扰，从而提高了OFDM的频谱效率。由于OFDM将宽带频率选择性衰落信道分成许多窄的平坦子信道，因此减轻了码间干扰(ISI)。因此，OFDM是4G/TD-LTE/LTE-Advanced通信系统的主导技术之一。但是OFDM很难满足未来5G网络的需求，因为OFDM具有很高的OOB，并且在整个带宽中只能支持一种波形。本文对5G候选波形进行了公平的比较。讨论了5G波形的基本原理和特点，即滤波器组多载波(FBMC)、通用滤波多载波(UFMC)、广义频分复用(GFDM)和滤波OFDM (F-OFDM)。

A Survey:On the Waveforms for 5G

OFDM is a multicarrier modulation technique which divides the high rate data stream in to multiple low rate data streams. The low rate data streams are modulated using subcarriers which are orthogonal to each other. The property of orthogonality allows simultaneous transmission of lot of subcarriers in a tight frequency space without interfering with each other, so the spectral efficiency in OFDM is improved. OFDM mitigates Inter Symbol Interference(ISI), since OFDM divides the wide band frequency selective fading channel in to many narrow flat sub channels. So OFDM is one of the dominant technology used in 4G/TD-LTE/LTE-Advanced communication systems. However OFDM can hardly meet the requirement for future 5G networks, since OFDM has high OOB and OFDM can support a only one kind of waveform in the whole Bandwidth. This paper presents a fair comparison of the waveform candidate for 5G. Basic principles and characteristics of 5G waveforms namely filter bank multi carrier (FBMC) universal filtered multicarrier(UFMC),generalized frequency division multiplexing (GFDM) and filtered OFDM (F-OFDM) are discussed.
