1. 6. FPGA Implementation of an Online Free-Space Optical Communications Test-Bed

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

   Author : Hamza Mahmoud; [2023]
   Keywords : Test-bed; FPGA design; PRBS; FSO; Optical communication; Testbädd; FPGA-design; PRBS; FSO; Optisk kommunikation;

   Abstract : Free Space Optical (FSO) satellite communications is proving to be a key enabling technology for global connectivity with the ability to provide connection across Europe with only 12 ground stations. For this, Deutsches Zentrum für Luft- und Raumfahrt (DLR) is working on implementing a robust communication system for FSO on a Xilinx RFSoC Field Programmable Gate Array (FPGA)( ZU28DR). READ MORE

3. 7. 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

4. 8. Faster than Nyquist Signaling with Spatial Coupling

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

   Author : Haoran Liu; Lingwei Zhang; [2022]
   Keywords : Technology and Engineering;

   Abstract : The emergence of the Faster-Than-Nyquist signaling (FTN) technology has im- proved the tight spectrum resources by compressing the transmission interval between adjacent pulses. In a natural environment, data transmission via a wire- less medium and through multi-path, at a high data rate, the leakage of these paths among symbols can cause severe inter-symbol interference (ISI).

5. 9. Extension of an Existing Simulator for Cellular Communication with Support for 5G NR : Porting of MIMO Channel Estimation Methods form a prototype to an existing Link-Level Simulator

   University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

   Author : Majed Haj Hussein; Abdulsalam Alnahawi; [2022]
   Keywords : 5G NR; Channel Estimation; MIMO; OFDM; DMRS;

   Abstract : Multiple Input Multiple Output (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) are two efficient technologies used to achieve higher data rate, lowlatency, robustness against fading used in 5G New Radio (NR). At the receiver end,the data arrives distorted due to disturbance during transfer over the wireless channel. READ MORE

6. 10. Application of NOMA for Mobile High Definition Images

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Aishwarya Reddy Danda; Naga Manikanta Chama; [2021]
   Keywords : 5G; Bit Error Rate; High Definition Images; Non-Orthogonal Multiple Access; Performance Assesment; Structural Similarity Index.;

   Abstract : The telecommunications technology has been developed tremendously as there has been an ever-increasing demand for more speed and reliability. The enormous increase in the number of smart phones and other data consuming devices, combined with the development of enhanced multimedia applications has resulted in a dramatic increase in the volume of mobile data traffic.
