Joint transceiver FIR filter design for multiuser MIMO channel shortening equalization and full equalization using channel duality

Multiuser MIMO channel equalization

In MIMO receivers, the channel state needs to be estimated for equalization, detection, and for feedback to the transmitter in case of adaptive modulation and coding. Most current iterative [7, 16, 27] and non-iterative [25] schemes in the single-user MIMO case are training-based and rely on the transmission of pilot symbols. Alternatives to pilot-based algorithms are semi-blind schemes which e...

Blind Equalization for MIMO FIR Channel in Wireless Communication Systems

In wireless communication systems, equalization process is needed to suppress the inter-symbol interference (ISI) caused by multipath channels. Conventional equalization techniques use training signals. Blind Methods are of great importance in the digital signal communication systems as they allow channel equalization at the receiver without the use fof training signals. A blind equalization in...

Filter Bank Multicarrier in Massive MIMO: Analysis and Channel Equalization

We perform an asymptotic study of the performance of filter bank multicarrier (FBMC) in the context of massive multi-input multi-output (MIMO). We show that the effects of channel distortions, i.e., intersymbol interference and intercarrier interference, do not vanish as the base station (BS) array size increases. As a result, the signal-to-interference-plus-noise ratio (SINR) cannot grow unbou...

Robust Transceiver Design for Multiuser MIMO Downlink with Channel Uncertainties

This letter addresses the problem of robust transceiver design for the multiuser multiple-input-multiple-output (MIMO) downlink where the channel state information at the base station (BS) is imperfect. A stochastic approach which minimizes the expectation of the total mean square error (MSE) of the downlink conditioned on the channel estimates under a total transmit power constraint is adopted...
