Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

Faster, ultra-reliable, low-power, and secure communications has always been high on the
wireless evolutionary agenda. However, the appetite for faster, more reliable, greener, and …

Massive multiple-input multiple-output (MIMO) is playing a crucial role in the fifth generation
(5G) and beyond 5G (B5G) communication systems. Unfortunately, the complexity of …

Millimeter wave (mmWave) MIMO will likely use hybrid analog and digital precoding, which
uses a small number of RF chains to reduce the energy consumption associated with mixed …

We propose a data-aided transmit beamforming scheme for the multi-user multiple-input-
single-output (MISO) downlink channel. While conventional beamforming schemes aim at …

Communications in millimeter-wave (mm-wave) spectrum (30-300 GHz) have experienced a
continuous increase in relevance for short-range, high-capacity wireless links, because of …

We explore the performance of multiple input multiple output (MIMO) transmitters in
correlated channels where increasing numbers of antenna elements are fitted in a fixed …

The increasing demands for massive connectivity, low latency, and high reliability of future
communication networks require new techniques. Multiple-input-multiple-output non …

We propose a low-complexity vector precoding (VP) scheme for the downlink of multi-user
multiple input single output (MU-MISO) systems with limited feedback. Conventional VP …

Low-complexity linear precoders are known to be close to optimal for massive multiple-input
multiple-output (M-MIMO) systems. However, the large number of antennas at the transmitter …
