  1. 1. 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

  2. 2. 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.

  3. 3. Function Computation via Over-the-Air Computation: Practical System Design

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Yuzhi Chen; [2023]
    Keywords : ;

    Abstract : Future wireless networks will need to contain millions of nodes, machines, and devices and provide high-speed and low-latency communication services. The traditional wireless network architecture design separates the communication and computation process, which has low utilization of wireless resources. READ MORE

  4. 4. Galileo High Accuracy Service SDR Implementation

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Carles Quilis Alfonso; [2023]
    Keywords : Galileo; GNSS; High Accuracy Service; Software Defined Radio; SDR; Matlab;

    Abstract : GNSS positioning has become a key element in everyday life of millions of people, from the person using google maps to move around an unknown city to the mailman or the DRON pilot who require it to carry out their work. All of them benefit in some way from the GNSS constellations and the position algorithms. READ MORE

  5. 5. Demonstration of Digital Selective Call spoofing

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Axel Lindbäck; Yamha Javid; [2023]
    Keywords : Digital Selective Calling; Software Defined Radio; Spoofing; Cybersecurity; Maritime Communication Systems;

    Abstract : Digital Selective Calling (DSC) is a vital maritime communications and safety system, enabling ships in distress to alert nearby vessels and coast guard stations of their emergency. While DSC is suitable for calling, its technical format is substandard from a cybersecurity perspective. READ MORE
