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 …

Underwater acoustic channel is a challenging medium for communication due to the
presence of significant multipath, high noise, frequency‐dependent propagation loss, and …

In this paper, we propose a frequency synchronization scheme for multiuser orthogonal
frequency division multiplexing uplink with a large-scale uniform linear array at base station …

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 …

In this letter, we consider simultaneous wireless information and power transfer (SWIPT) in
multiuser multiple-input single-output (MISO) broadcast channel with confidential messages …

The advanced neural network methods solve significant signal estimation and channel
characterization difficulties in the next-generation 5G wireless communication systems. The …

In this paper, we propose a new blind frequency synchronization scheme for multiuser
orthogonal-frequency-division multiplexing (OFDM) uplink transmissions. The spatial …

Activity detection in machine-type communication (MTC) has been recognized as an
effective way to support massive connectivity of the Internet-of-Things (IoT) devices …

Non-orthogonal multiple access (NOMA) is a promising solution for secure transmission
under massive access. However, in addition to the uncertain channel state information (CSI) …
