Abstract The paper examines the existing relationships between universities and Frontex, investigating and problematising the intersection between the higher education sector and the violence of the European border regime. We introduce the concept of positivist dissonance to conceptualise these relationships within the wider “industrial‐military ...

From Compact MIMO to Massive MIMO
We study information theoretic design of compact antenna arrays and nonlinear precoding for multiuser MIMO channels with coarsely quantized alphabets. For the RF front-end design, it is shown that a class of lossless multiport matching networks maximizes information rates at any antenna spacing.

The MIMO-OTFS Technique in the Next 6G Communications
The orthogonal time-frequency space (OTFS) technique is a promising method of waveform modulation that encodes data in the delay-doppler (DD) domain. OTFS distinguishes itself from conventional multiplexing methods by employing two-dimensional modulation
