TL;DR: In this paper, a robust beamforming design for underlay cognitive radio networks where multiple secondary transmitters communicate with corresponding secondary receivers and coexist with a primary network is proposed, where the interference powers to the primary receivers are kept below a threshold to guarantee that the performance of the primary network does not degrade due to the secondary network.

TL;DR: The 6G Hexa-X project as mentioned in this paper aims to connect human, physical, and digital worlds with a fabric of 6G key enablers, including sub-THz transceiver technologies, accurate stand-alone positioning and radio-based imaging, improved radio performance, artificial intelligence (AI) / machine learning inspired radio access network (RAN) technologies, future network architectures and special purpose solutions including future ultra-reliable low-latency communication (URLLC) schemes.

TL;DR: In this paper, the authors show that secure FD relaying is feasible, even under strong self-interference and in the presence of a sophisticated multiple antenna eavesdropper, and derive closed-form expressions for the average secrecy rate and the secrecy outage probability.

TL;DR: The parallel interference cancellation principle is a conceptually simple and yet effective method of parameter estimation and data detection in the presence of multiple-access and multipath interference.

TL;DR: A simple spreading code allocation scheme is proposed for downlink MC-CDMA employing WH codes using Walsh-Hadamard codes for frequency characterisation.
