1. 21. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios

   University essay from Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Author : Sai Chetan Poluri; Tejaswi Dunuka; [2023]
   Keywords : 5G and 6G Communications; FMCW; GNU Radio; ISAC; OFDM; SDR; Sensing; JSAC;

   Abstract : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. READ MORE

3. 22. A Conjugate Residual Solver with Kernel Fusion for massive MIMO Detection

   University essay from Högskolan i Halmstad/Centrum för forskning om tillämpade intelligenta system (CAISR)

   Author : Ioannis Broumas; [2023]
   Keywords : MIMO; massive MIMO; GPU; CUDA; Software Defined Radio; SDR; MMSE; ZF; zero-forcing; parallel detection; iterative methods; conjugate residual; parallel computing; kernel fusion;

   Abstract : This thesis presents a comparison of a GPU implementation of the Conjugate Residual method as a sequence of generic library kernels against implementations ofthe method with custom kernels to expose the performance gains of a keyoptimization strategy, kernel fusion, for memory-bound operations which is to makeefficient reuse of the processed data. For massive MIMO the iterative solver is to be employed at the linear detection stageto overcome the computational bottleneck of the matrix inversion required in theequalization process, which is 𝒪(𝑛3) for direct solvers.

4. 23. Investigation of Antenna Radomes in Low Earth Orbits

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Mathias Manohar Gren; [2023]
   Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

   Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

5. 24. Effect of the ICRH Antenna Position on the Coupled Power in ITER and JET

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

   Author : Olle Sundberg; Vincent Forsberg; [2023]
   Keywords : ;

   Abstract : Fusion energy has fascinated scientists for decades. One reason we do not see thispromising energy source powering today's society is the fact that the process requires extremeplasma temperatures. READ MORE

6. 25. Measuring Sprint Speed with Ultra-wideband Technology

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

   Author : Johannes Arenander; [2023]
   Keywords : Speed; Sprint; Ranging; Ultra-wideband; Hastighet; Sprint; Distansmätning; Ultrabredband;

   Abstract : Sprinting can be an important ability in sports, and there are many methods for measuring sprint performance. Two common methods are hand-held timing and fully automatic timing systems. However, hand-held timing is inaccurate due to reaction time, and fully automatic timing can be impractical since it involves complex equipment. READ MORE
