With the proliferation of Internet-of-Things (IoT) devices, acoustic sensing attracts significant
attention in recent years. It exploits acoustic transceivers such as microphones and speakers …

Millimeter-wave (mmWave) systems use directional beams to support high-rate data
communications. Small misalignment between the transmit and receive beams (eg, due to …

We optimize the Age of Information (AoI) in mobile networks using the age-threshold slotted
ALOHA (TSA) protocol. The network comprises multiple source-destination pairs, where …

Uplink sensing in perceptive mobile networks (PMNs), which uses uplink communication
signals for sensing the environment around a base station, faces challenging issues of clock …

Wireless communication has traditionally been designed to connect human users. The main
design goal was to maximize the data rate while guaranteeing moderate reliability and …

In sparse code multiple access (SCMA)-based grant-free (GF) access, both user's channel
and the selected SCMA codebook (CB) are considered as a transmission signature for multi …

In this paper, we present a frame structure that can be viewed as a preamble for the
detection and synchronization process (leading to low cost receiver) and as an encoded …

Since orthogonal frequency division multiplexing (OFDM) systems are very susceptible to
symbol timing offset (STO) and carrier frequency offset (CFO), which cause inter-symbol …

The strong multipath and long delay extensions can lead to large errors in the timing offset
estimation and carrier frequency offset estimation of the Orthogonal Frequency Division …

Massive Internet of Things systems, eg, Low Power Wide Area Networks, aim at connecting
very large numbers of low-cost devices with multi-year battery life requirements, a goal that …
