Abstract:
In this contribution we propose two new iterative precoder and equalizer designs for the Downlink (DL) scenario of Multi-User (MU)-MIMO systems which employ Filter Bank based Multi-Carrier (FBMC) with Offset-Quadrature Amplitude Modulation (O-QAM). In a MU-MIMO DL scenario, we must design our per-subcarrier filters to compensate the inter-symbol and inter-carrier interference (ISI and ICI) present in an FBMC/OQAM system in addition to multi-user interference (MUI). The first method presented takes advantage of the Mean Squared Error (MSE)-duality to design Minimum MSE (MMSE)-based precoders and equalizers. The second method looks at maximizing the Signal-to-Leakage Ratio (SLR) in the transmitter and the Signalto- Interference plus Noise Ratio (SINR) in the receiver. Through numerical simulations we will evaluate the performance of these methods and compare them to recent approaches found in the literature.
