Prototyping the 5G Air Interface in GNU Radio: An FBMC Primer
The recent research projects consider Filter Bank Multicarrier (FBMC) as a key enabler for the future flexible 5G air interface, mostly due to its increased spectral efficiency compared to Orthogonal Frequency Division Multiplexing (OFDM). Moreover, it is of high interest to have a rapid prototyping framework for performance validation and proof-of-concept of the novel diverse communication techniques.
This talk presents the design steps and implementation issues of an FBMC transceiver within the existing Gnu Radio-based framework. The high reconfigurability of the framework further allows for the future easy integration and evaluation of other 5G PHY layer candidates. Several transmission scenarios are considered comparing the spectral properties between the FBMC and OFDM systems.
