Abstract

Filter bank multi carrier (FBMC) shows better spectral properties
compared orthogonal frequency division multiplexing (OFDM). Double selective
channels are described time selectivity and frequency selectivity which explore
their performance variance in this paper. Closed form bit error probability
(BEP) derives one top equalizers linear modulation techniques with OFDM and
FBMC structures. When interference is closed to Gaussian noise, BEP error
researching and Monte Carlo simulations are validated our analytically
calculations. This paper presents us three scenarios that are OFDM without
cyclic prefix (CP), CP-OFDM and FBMC applications about BEP over signal to
noise ratio (SNR) for different channel models and different velocities.
Applications are realized for theoretical, Gaussian approach, simulations and
variations are shown with figures. The obtained BEP expressions utilize to
define time variant propagation for OFDM and FBMC.
