Over-the-air computation (AirComp) is a disruptive technique for fast wireless data
aggregation in Internet of Things (IoT) networks via exploiting the waveform superposition …

We investigate the performance of multi-user multiple-antenna downlink systems in which a
base station (BS) serves multiple users via a shared wireless medium. In order to fully …

We develop sparse array receive beamformer design methods achieving maximum signal-to-
interference plus noise ratio for wideband sources and jammers. Both tapped delay line …

Reconfigurable intelligent surface (RIS) is a disruptive technology to enhance the
performance of physical-layer key generation (PKG) thanks to its ability to smartly customize …

In multi-antenna systems, it is preferred to activate only a subset of the available transmit
antennas in order to save hardware and energy resources, without seriously degrading the …

Massive MIMO is currently a leading physical layer technology candidate that can
dramatically enhance throughput in 5G systems, for both unicast and multicast transmission …

We consider sparse array beamformer design achieving maximum signal-to interference
plus noise ratio (MaxSINR). Both array configuration and weights are attuned to the …

The chapter considers sparse array beamforming design via machine learning with the
learning objective of maximum signal‐to‐interference plus noise ratio (MaxSINR). The …

The paper examines neural network learning of the sparse array configurations in optimum
beamforming. Unlike iterative greedy, convex, and global optimization methods for optimum …

Sparse array design has been advantageous in re¬ ducing receiver data, system's hardware
and computational costs by the careful placement of available sensors such that the ob¬ …
