Large range of potential use cases are differentiated by later wireless setup. This demands a movable allocation of the accessible time-frequency resources, which is difficult in conventional (OFDM) Hence, adjustments of OFDM, for example, windowing or separating, become vital. Alternatively, we can employ a different modulation scheme, such as Filter Bank Multi Carrier (FBMC). In this we provide a unifying framework, discussion and performance evaluation of FBMC and compare it to OFDM based schemes. Our investigations are not only based on simulations, but are substantiated by real-world testbed measurements and trials, where we show that multiple antennas and channel estimation, two of the main challenges associated with FBMC, can be efficiently dealt with. Additionally, we derive closed-form solutions for the signal-to-interference ratio in doubly-selective channels and show that in many practical cases, one-tap equalizers are sufficient.
