1. 1. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
   Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

   Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

3. 2. 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.

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

   Author : Lifang Wang; [2021]
   Keywords : New radio NR ; Shared channel; Channel coding; Low-Density Parity-Check LDPC codes; Layered Normalized Min-Sum Algorithm LNMSA ; Layered Offset Min-Sum Algorithm LOMSA ; Ny radio NR ; Delad kanal; Kanalkodning; Paritetskontrollkoder med låg LDPC densitet; Layered Normalized Min-Sum Algorithm LNMSA ; Layered Offset Min-Sum Algorithm LOMSA ;

   Abstract : Channel coding plays a vital role in telecommunication. Low-Density Parity- Check (LDPC) codes are linear error-correcting codes. According to the 3rd Generation Partnership Project (3GPP) TS 38. READ MORE

5. 4. Efficient Transmission over Unknown Channels

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

   Author : Ranjitha Gubbi Suresh; [2020]
   Keywords : Multi-Layer Transmission; RBIR; HARQ; mixing layers; successive demodulation; Wi-Fi; Technology and Engineering;

   Abstract : In recent years, digital transmission techniques have been continuously evolving by employing increasingly more advanced Modulation and Coding Scheme (MCS). However, when the wireless channel is varying rapidly, it is hard or even impossible for the transmitter to select the proper MCS. READ MORE

6. 5. Development of a demo platform on mobile devices for 2D- and 3D-sound processing

   University essay from Uppsala universitet/Elektricitetslära

   Author : Frans Rosencrantz; [2020]
   Keywords : Spatial Audio; Raspberry PI; Microphone Array; Dirac;

   Abstract : This thesis project aims for the development of a demonstration platform on mobile devices for testing and demonstrating algorithms for 2D and 3D spatial sound reproduction. The demo system consists of four omnidirectional microphones in a square planar array, an Octo sound card (from Audio Injector), a Raspberry Pi 3B+ (R-Pi) single-board computer and an inertial measurement unit (IMU) located in the center of the array.
