Due to the broadcast nature of radio propagation, the wireless air interface is open and
accessible to both authorized and illegitimate users. This completely differs from a wired …

Massive MIMO has been recognized as a promising technology to meet the demand for
higher data capacity for mobile networks in 2020 and beyond. Although promising, each …

Providing reliable broadband wireless communications in high mobility environments, such
as high-speed railway systems, remains one of the main challenges faced by the …

This paper considers multicell multiuser MIMO systems with very large antenna arrays at the
base station. We propose an eigenvalue-decomposition-based approach to channel …

Cognitive ambient backscatter communication is a novel spectrum sharing paradigm, in
which the backscatter system shares not only the same spectrum, but also the same radio …

By combining multiple-input multiple-output (MIMO) communication with the orthogonal
frequency division multiplexing (OFDM) modulation scheme, MIMO-OFDM systems can …

Within the wide range of issues related to 4G wireless networks, due to the scope of the
ISSTA conference, in this presentation we highlight some segments of wireless networks …

We consider the problem of adaptive subspace tracking, when the rank of the subspace we
seek to estimate is assumed to be known. Starting from the data projection method (DPM) …

The conventional grant-based network relies on the handshaking between the base station
and active devices to achieve dynamic multi-user scheduling, which may result in large …

A novel approach of blind channel estimation for orthogonal frequency-division multiplexing
(OFDM) systems is proposed. A linear transformation is applied on each block before it …
