Timing and carrier synchronization is a fundamental requirement for any wireless
communication system to work properly. Timing synchronization is the process by which a …

Wireless transceivers for mass-market applications must be cost effective. We may achieve
this goal by deploying non-ideal low-cost radio frequency (RF) analog components …

Phase noise is inevitably present in wireless communications, arising from both hardware
impairments and imperfect channel estimation, and has substantial implications on the …

In this paper, we propose a physical layer authentication scheme in heterogeneous coexist
multiple-input-multiple-output (MIMO) systems. This scheme utilizes two physical layer …

By exploiting two intrinsic physical (PHY)-layer features in terms of location-specific channel
gain and transmitter-specific phase noise, this paper proposes a new PHY-layer …

In this paper, we analyze the impacts of timing offset (TO), carrier frequency offset (CFO),
and phase noise in orthogonal frequency division multiplexing (OFDM) and generalized …

Localization is envisioned as a key enabler to satisfy the requirements of communications
and context-aware services in the fifth/sixth generation (5G/6G) communication systems …

We consider the problem of monostatic radar sensing with orthogonal frequency-division
multiplexing (OFDM) joint radar-communications (JRC) systems in the presence of phase …

This letter presents a deep learning (DL) algorithm for compensating the impacts of phase
noise in channel estimation and data detection for multicarrier systems. The proposed DL …

Channel estimation at millimeter wave (mmWave) carrier frequencies is challenging when
large antenna arrays are used. Prior work has leveraged the sparse nature of mmWave …
