1. 6. Physical Layer Security With Active Jamming Using NOMA.

   University essay from Blekinge Tekniska Högskola

   Author : Mounika Polisetti; [2021]
   Keywords : Physical Layer security; secrecy capacity; eavesdropper; spectral efficiency; secure NOMA transmission;

   Abstract : This paper is persuaded to understand the physical layer security in wireless commu-nications utilizing NOMA (Non Orthogonal Multiple Access) concepts in the presence of an eavesdropper. Physical layer security maintains the confidentiality and secrecyof the system against eavesdroppers. READ MORE

3. 7. Methods of self-interference cancellation in full duplex telecommunication systems

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Henrik Erlandsson; Viktor Sköldheden; [2021]
   Keywords : telecommunication; full duplex; self-interference cancellation; electronics; wireless communication; power amplifier;

   Abstract : With the wireless technology evolving quickly, so does the demand of speed and efficiency. This makes the companies look for new and better ways to improve the current systems. One way of improving the present systems would be to employ Full Duplex Technology. READ MORE

4. 8. Performance of a Non-Orthogonal Multiple Access System with Full-duplex Relaying over Nakagami-m Fading

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Author : Rahul Chowdary Erpina; Viswakanth Reddy Gopireddy; [2021]
   Keywords : NOMA; Full Duplex Relaying; Nakagami-m Fading; Power domain NOMA; Successive Interference Cancellation; Half Duplex Relaying; OFDMA; Code domain-NOMA; Time domain-NOMA.;

   Abstract : In our thesis work, we analyze the performance analysis of a power domain NonOrthogonal Multiple Access (NOMA) system in which the closer user acts as fullduplex relaying to forward the signal to farther user. Because Nakagami-m distribution is a generalized case including the two common fading distributions as specialcases: Rayleigh distribution (m=1), Rician distribution (m>1). READ MORE

5. 9. An Evaluation of Ethernet as Data Transport System in Avionics

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Rickard Doverfelt; [2020]
   Keywords : AFDX; Avionics; Bandwidth utilisation; Ethernet; Latency; Legacy systems; AFDX; Avionik; Bandbreddsutyttjande; Ethernet; Latency; Legacysystem;

   Abstract : ÅF Digital Solutions AB are looking to replace their current legacy system for audio transmissions within aircrafts with a new system based on Ethernet. They also want the system to be as closely matching the current Audio Integration System as possible as well as preferably using commercial off the shelf components. READ MORE

6. 10. Hybrid Beamforming Design for Full-Duplex mmWave Relaying Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhe Wu; [2020]
   Keywords : mmWave; full-duplex; hybrid beamforming; self-interference cancellation; OMP; fast ADMM; convergence; mmwave; fullständig duplex; hybridstrålformning; självförstörande annullering; OMP; snabb ADMM; konvergens;

   Abstract : With the tremendous growth in the mobile data traffic, the demand for highdata rate is increasing rapidly, and higher frequency resources shall be exploredto alleviate the congestion in the overcrowded spectrum, thus, the millimeterwave (mmWave) frequency resource ranging from 30 GHz to 300 GHz has beenrecognized as a nature fit for the fifth-generation (5G) and beyond network. Tocompensate the severe path-loss in the mmWave band as well to realize theefficient transmissions by applying the low-cost architecture, it is of intereststo investigate the beamforming schemes with large-scale antenna arrays andthe full-duplex (FD) relaying strategy, which are indispensable in the operationof directional signal transmission and the efficient spectrum utilization inthe mmWave transmission, respectively.
