Fifth generation (5G) wireless networks face various challenges in order to support large-
scale heterogeneous traffic and users, therefore new modulation and multiple access (MA) …

The existing theory and techniques of wireless communication anti-jamming have reached
their performance limit recently. With this focus, by leveraging the inherent characteristics of …

In this paper, we study cooperative precoder design in two-tier networks, consisting of a
macro-cell (MC) and several small-cells (SCs). By exploiting multiuser Vandermonde …

This paper deals with scenario-aware, uncoordinated, and distributed signaling techniques
in the context of feedforward opportunistic communications, that is, when the opportunistic …

During the first phase of the deployment of new radio (NR) networks, base station (BS) and
user equipment (UE) are expected to operate alongside the pre-existing long-term evolution …

In this paper, we investigate opportunistic transmission based on signal alignment for
multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) …

This letter evaluates the impact of subspace leakage in conventional (single-dimension) and
dimensionally spread null-space precoding schemes. This phenomenon arises when the …

This work studies the impact of the array geometry on a space-time extension of a
generalized class of null-space precoding format denoted as π-waveforms (Projection …

The statistical side information of interference channels is exploited in this paper to derive a
novel uncoordinated on-line pilot design strategy for opportunistic communications …

The uncoordinated design of pulse shaping filters for opportunistic communications is
addressed. We show that under degrees-of-freedom sensing uncertainties the waveform …
