dc.description.abstract | This paper introduces a practical precoding method
for the downlink of Filter Bank Multicarrier-based (FBMC-based) massive multiple-input multiple-output (MIMO) systems.
The proposed method comprises a two-stage precoder, consisting
of a fractionally spaced prefilter (FSP) per subcarrier to equalize
the channel across each subcarrier band. This is followed by a
conventional precoder that concentrates the signals of different
users at their spatial locations, ensuring each user receives only
the intended information. In practical scenarios, a perfect channel
reciprocity may not hold due to radio chain mismatches in the up-
link and downlink. Moreover, the channel state information (CSI)
may not be perfectly known at the base station. To address these
issues, we theoretically analyze the performance of the proposed
precoder in presence of imperfect CSI and channel reciprocity
calibration errors. Our investigation covers both co-located (cell-based) and cell-free massive MIMO cases. In the cell-free massive MIMO setup, we propose an access point selection method based
on the received SINRs of different users in the uplink. Finally,
we conduct numerical evaluations to assess the performance of
the proposed precoder. Our results demonstrate the excellent
performance of the proposed precoder when compared with the
orthogonal frequency division multiplexing (OFDM) method as
a benchmark. | en |
