Abstract
Orthogonal frequency division multiplexing (OFDM) systems present some shortcomings such as strict requirements for synchronization and reduced spectral efficiency. Filter bank multicarrier (FBMC) systems based on quadrature amplitude modulation (QAM-FBMC) have attracted increasing attention since they are considered an effective alternative to OFDM schemes. In this paper, the bit error rate (BER) of QAM-FBMC systems with single-tap equalization, is obtained. Moreover, the asymptotic (for a large number of subcarriers) expression of the BER and an approximate expression of the asymptotic BER are derived. The numerical results show that the derived BER expressions are quite accurate.
