Abstract :
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.
