  • Abstract Compared with orthogonal frequency division multiplexing (OFDM) modulation, filter bank-based multicarrier (FBMC) modulation is recently developed to further condense the spectrum, thereby increasing the spectral efficiency. Unlike to OFDM, FBMC adopts offset quadrature amplitude modulation (OQAM) and the fractionally spaced per subcarrier is required. The OQAM-based FBMC is also called FBMC/ OQAM. Moreover, the symbol period of FBMC is greatly larger than that of OFDM and overlaps in time-domain, which causes the inter-carrier interference (ICI) and the inter-symbol interference (ISI). An equalization is necessary for the FBMC/OQAM to suppress the influence of ICI and IBI. The interference becomes noticeable as the modulation involved in the frequency selective fading channel in the multiple-input multiple-output (MIMO) systems. In this thesis, we study the minimum mean-squared error equalization for the FBMC/OQAM modulation in frequency selective MIMO systems. The performance is evaluated in terms of equalizer length, the numbers of overlapped symbols, the length of frequency selective fading channel, and the numbers of subcarriers. Simulation results demonstrate the effectiveness of the MMSE equalizer and show the remarkable spectral efficiency compare with the conventional OFDM modulation.
