In this paper, we investigate beamforming approaches for multiple access secrecy channels.

Proposals are made for a form of broadcasting in which a single transmitter and transmitting aerial are used for the simultaneous transmission of several programmes.

A signal may be read from a storage medium faster than the rate that would correspond to real time reconstruction of the signal; this process has been named time compression or time speed-up.

We implemented a real-time DQPSK precoder for 107-Gb/s data, together with a high-speed channel alignment scheme and the required rate adaptation from 10.7 Gb/s to 13.375 Gb/s, on a Xilinx Virtex I

The tremendous increase of mobile user traffic load forces us to develop intelligent systems to achieve an effective use of the wireless network and processing resources.

This paper presents solutions for efficient multiplexing of ultra-reliable low-latency communications (URLLC) and enhanced mobile broadband (eMBB) traffic on a shared downlink channel.

We discuss the problem of multiplexing several variable rate encoded streams into a single stream.

The main network solutions for supporting QoS rely on traffic policing (conditioning, shaping).

We establish upper bounds for the number of smooth values of the Euler function.
