In practical scenarios, a perfect channel reciprocity may not hold due to radio chain mismatches in the uplink and downlink.

In the proposed setup, each stream may be thought of as a resource block in SCM, analogous to resource blocks in OFDM.

We theoretically analyze the performance of the proposed precoder in the presence of imperfect CSI and channel reciprocity calibration errors.

In this paper, we design receivers for filter bank multicarrier-based (FBMC-based) massive MIMO considering practical aspects such as channel estimation and equalization.

In this paper, we present a modified downlink precoding approach in the FD based on regularized zero forcing (RZF), which reuses the matrix inverses calculated as part of the FD MMSE uplink detection.

Frequency domain (FD) multi-user detection (MUD) has been shown to be an effective means of approaching the theoretical per-user capacity for single carrier modulation (SCM) schemes in massive MIMO scenarios with highly dispersive channels.
