We propose a superimposed pilot (SP)-based channel estimation and data detection
framework for orthogonal time-frequency space (OTFS) systems, which superimposes low …

In this paper, superimposed pilots are introduced as an alternative to time-multiplexed pilot
and data symbols for mitigating pilot contamination in massive multiple-input multiple-output …

This book introduces the theoretical elements at the basis of various classes of algorithms
commonly employed in the physical layer (and, in part, in MAC layer) of wireless …

We consider authentication of a wireless multiple-input-multiple-output (MIMO) system by
deliberately introducing a stealthy fingerprint at the physical layer. The fingerprint is …

In this paper, the performance of cell-free massive multiple-input multiple-output (CF-
mMIMO) systems under the transceiver non-ideal radio-frequency responses (NI-RF-RPs) …

This work proposes a superimposed pilot (SP)-based channel estimation and data detection
framework for orthogonal time-frequency space (OTFS) scheme, wherein low-powered pilots …

Regular pilots in a massive multi-input multi-output (MIMO) system with large number of
users suffer from the pilot contamination effect due to limited training time. In this paper, for a …

In this paper, we investigate the downlink throughput performance of a massive multiple-
input multiple-output system that employs superimposed pilots for channel estimation. The …

We propose a non-redundant linear precoding scheme and three peak-to-average power
ratio (PAPR) reduction schemes for multiple-input multiple-output (MIMO) orthogonal …

In this paper, the spectral efficiency (SE) of an uplink hardware-constrained cell-free
massive multi-input multi-output (MIMO) system with maximal ratio combining (MRC) …
