摘要
新一代多载波技术是第五代移动通信系统(5G)的关键技术之一。研究表明,正交频分复用(OFDM)在5G场景下可能不再是最佳选择。主要讨论了滤波器组多载波(FBMC)、广义频分复用(GFDM)等几种热门的多载波传输技术,给出其内在联系,分析其利弊,为进一步研究提供参考。
New generation of multicarrier technique is the one of key techniques of 5G mobile communications. Related research demonstrates that OFDM may not be the optimal in future 5G. Several popular multicarrier transmission techniques including iflter bank based multicarrier （FBMC）, generalized frequency division multiplexing （GFDM） and so on were discussed in this paper. Their relationship, advantages and disadvantages were presented to provide a useful reference to further research.
