English abstract:
Filter Bank Multi-Carrier (FBMC) is a modulation technique with enhanced spectral properties compared to Orthogonal Frequency Division Multiplexing (OFDM). In this letter, we investigate the performance degeneration of OFDM and FBMC in doubly-selective channels, that is, time-selectivity and frequency-selectivity. For that, we derive closed-form Bit Error Probability (BEP) expressions for arbitrary linear modulation methods based on one-tap equalizers, with OFDM and FBMC being special cases, covered by our general BEP expressions. We validate our calculations by Monte-Carlo simulations and investigate the BEP error if the interference is approximated as Gaussian noise.
