1. 16. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
   Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

   Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

3. 17. Backscatter Communications for 6G

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Keywords : Technology and Engineering;

   Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

4. 18. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

   University essay from KTH/Tillämpad fysik

   Author : Marie Defives; [2022]
   Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

   Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

5. 19. Multi-dimensional Packing for Resource Allocation in 5G

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Matteo Ghetti; [2022]
   Keywords : ;

   Abstract : The Fifth Generation (5G) of wireless communication system brings a series of new challenges in resource optimization. For example optimizing the number of bits and dedicated time used by each service would improve the quality of communications. READ MORE

6. 20. D-band Power Amplifiers in Vertical InGaAs Nanowire MOSFET Technology for 100 Gbps Wireless Communication

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Patrik Blomberg; Ludvig Pile; [2022]
   Keywords : D-band; Power Amplifier; Pseudo-differential common source; Stacked; Vertical InGaAs nanowire; MOSFET; Technology and Engineering;

   Abstract : Two different topologies of power amplifiers (PAs) are designed in the frequency range 130-174.8 GHz for use in backhaul transmitters. These are the pseudo-differential common source (PDCS) and the single-ended stacked amplifier topologies. READ MORE
