A fully-quantum network implies the creation of quantum entanglement between a given
source node and some other destination node, with a number of quantum repeaters in …

The standardisation of 5G is reaching its end, and the networks have started being
deployed. Thus, 6G architecture is under study and design, to define the characteristics and …

Classical neural networks (CNNs) provide wide applications in communication technology,
ranging from enhancement of key performance indicators (KPIs) of communication protocols …

This paper proves that every non-trivial, linear time-invariant (LTI) system of the first order
shows a complexity blowup if it is simulated on a digital computer. This means that there …

Negative Group Delay (NGD) is a concept not widely explored in embedded digital signal
processing systems, and this study aims to fill this gap. It presents a novel methodology for …

The research and industrial communities are concentrating their efforts in two main trends in
communications, which are seen as the new drivers not only in telecommunications but also …

In the past few years, quantum computers have become increasingly robust and are
reaching industrial strength in terms being considered seriously for addressing real life …

In future 6G networks, quantum technologies are expected to be used mainly for security, eg
quantum key distribution. However, additional advantages can also result from the …

With the rapid development of industrial automation, the control accuracy in industrial
production has gradually improved and the control process has become more and more …

We present a methodology for implementing NGD using a Finite Impulse Response (FIR)
filter. The NGD concept is counter-intuitive in nature, so we first provide the basic theory of …
