Generalized Frequency Division Multiplexing: Unified Multicarrier Framework Ahmad Nimr1, Zhongju Li1, Marwa Chafii2 and Gerhard Fettweis¹ 1 Vodafone Chair Mobile Communication Systems, Technische Universität Dresden, Germany 2ETIS UMR 8051, CY Paris Université, ENSEA, CNRS, France Overview of Multicarrier Waveforms The original motivation behind multicarrier modulation (MCM) is to tackle the frequency selectivity of the wireless channel for broadband communications [1]. The idea is to trans- mit high data rate using parallel streams; each stream has a lower data rate and occupies narrower bandwidth. The name carrier is inherited fro
