1. 21. Secrecy Capacity of Cooperative Transmission with Opportunistic Relaying Scheme

   University essay from

   Author : Dhathri Pravallika Pasumarthi; [2022]
   Keywords : Cooperative Transmission; Opportunistic Relaying; Decode-and-Forward; Outage Probability; Secrecy Capacity; Fading.;

   Abstract : The usage of wireless communication has increased over the past few years. Most wired communications are replaced by wireless communication for ease of use. Wireless communication transfers confidential information like personal information and credentials between two entities. READ MORE

3. 22. Deep Neural Networks for dictionary-based 5G channel estimation with no ground truth in mixed SNR scenarios

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

   Author : Matteo Ferrini; [2022]
   Keywords : 5G; Channel Estimation; Sparse Linear Inverse Problem; Approximate Message Passing; Neural Networks; 5G; kanaluppskattning; sparsamt linjärt inversproblem; approximativ meddelandeöverföring; neurala nätverk;

   Abstract : Channel estimation is a fundamental task for exploiting the advantages of massive Multiple-Input Multiple-Output (MIMO) systems in fifth generation (5G) wireless technology. Channel estimates require solving sparse linear inverse problems that is usually performed with the Least Squares method, which brings low complexity but high mean squared error values. READ MORE

4. 23. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling

   University essay from KTH/Fysik

   Author : Johanna Jacobsson; [2022]
   Keywords : computed tomography; magnetic resonance imaging; cone beam computedtomography; cartilage; osteochondral lesions; metatarsal phalangeal joint; datortomografi; magnetisk resonanstomografi; kon-datortomografi; brosk; kondrala skador; metatarsalphalangen-leden;

   Abstract : Walking without pain in the toe has a significant impact on a person’s well-being. Human mobility will be impaired in osteoarthritis of the big toe, and pain will occur during walking. By replacing the cartilage or bone injury with an individualised implant, osteochondral injuries to the knee and ankle can be treated. READ MORE

5. 24. 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.

6. 25. Right fit Database Technology for Discounts

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

   Author : Annelie Sinander; Alexandra Galonja; [2022]
   Keywords : Database Technologies; Discounts; SQL; NoSQL; Latency; Signal-to-noise-ratio; Technology and Engineering;

   Abstract : Detta examensarbete har utförts i syfte att jämföra hur fyra olika databashanterare (DBMS) presterar inom ett begränsat antal områden för att därigenom dra slutsatser kring vilken som fungerar bäst för att lagra data om rabatter på IKEA. De databashanterare som testas är MongoDB, MariaDB, Neo4j och PostgreSQL. READ MORE
