Although orthogonal frequency division multiplexing (OFDM) has been standardized for 5G, filter bank multi-carrier (FBMC) and filtered orthogonal frequency division multiplexing (F-OFDM) remain competitive as candidates for future generations of wireless technologies beyond 5G, due to their reduced spectrum leakage and thus enhanced spectrum efficiency. In this article, we developed a unified spectrum expression for OFDM, FBMC, and F-OFDM, which provides comparative insights into those techniques. A representative sideband quantification is included at the end of this article.

OFDM，FBMC和F-OFDM的统一频谱公式

尽管正交频分复用（OFDM）已针对5G进行了标准化，但滤波器组多载波（FBMC）和滤波正交频分复用（F-OFDM）由于其降低的性能，仍可作为5G以后的下一代无线技术的竞争者频谱泄漏，从而提高了频谱效率。在本文中，我们为OFDM，FBMC和F-OFDM开发了统一的频谱表达式，从而提供了对这些技术的比较见解。本文末尾包含了代表性的边带量化。
