到目前为止，正交频分复用（OFDM）已经成为宽带多载波通信的主导技术。然而，在诸如认知无线电和多用户多载波系统的上行链路的某些应用中，其中子载波的子集被分配给每个用户，OFDM可能是不期望的解决方案。在这篇文章中，我们解决了OFDM在这些和其他应用中的缺点，并表明滤波器组多载波（FBMC）可能是一个更有效的解决方案。尽管许多研究人员已经研究了FBMC方法，有些甚至在OFDM发明之前，但直到最近，FBMC才被少数标准委员会认真考虑。
As of today, orthogonal frequency division multiplexing (OFDM) has been the dominant technology for broadband multicarrier communications. However, in certain applications such as cognitive radios and uplink of multiuser multicarrier systems, where a subset of subcarriers is allocated to each user, OFDM may be an undesirable solution. In this article, we address the shortcomings of OFDM in these and other applications and show that filter bank multicarrier (FBMC) could be a more effective solution. Although FBMC methods have been studied by a number of researchers, and some even before the invention of OFDM, only recently has FBMC been seriously considered by a few standard committees.
