Abstract :Filter bank multi carrier insert ignore into journalissuearticles values(FBMC); shows better spectral properties compared orthogonal frequency division multiplexing insert ignore into journalissuearticles values(OFDM);. Double selective channels are described time selectivity and frequency selectivity which explore their performance variance in this paper. Closed form bit error probability insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(CP);, CP-OFDM and FBMC applications about BEP over signal to noise ratio insert ignore into journalissuearticles values(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.
Keywords : OFDM, FBMC, Channel models, BEP, CP, Signal to noise ratio, time varying channels
