  3. 17. Cross-subframe channel estimation for low-complexity devices in LTE

    Master-uppsats, KTH/Teknisk informationsvetenskap

    Författare :Hugo Lime; [2017]
    Nyckelord :;

    Sammanfattning : One of the most critical issues of wireless communication systems is the timevaryingand frequency-selective channel. Knowledge about the channel greatlyimproves communication performance. It enables coherent demodulation andmeasurements of Signal to Noise Ratio (SNR) and Channel Quality Indicators(CQI). LÄS MER

  4. 18. Implementation and Evaluation of Architectures for Multi-Stream FIR Filtering

    Master-uppsats, Linköpings universitet/Datorteknik

    Författare :Yang Jiang; [2017]
    Nyckelord :FIR filter; multi-stream FIR filtering; pipeline interleaving; time multiplexing; quantization;

    Sammanfattning : Digital filters play a key role in many DSP applications and FIR filters are usually selected because of their simplicity and stability against IIR filters.In this thesis eight architectures for multi-stream FIR filtering are studied. LÄS MER

  5. 19. Wall Compensation Algorithms for M-sequence UWB Radar

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Mhd Jihad Abou Raas; [2016]
    Nyckelord :Ultra-wideband UWB ; Wall Compensation Algorithms;

    Sammanfattning : A technique for wall compensation in the ultra-wideband (UWB) through-wall imaging radar is presented. The UWB system can be utilize in high precision measurements, but due to phase distortion and amplitude attenuation caused by the wall the precision is limited, the target is displaced, and the image is defocused.

  7. 20. FPGA Software Development for Control Purposes of High-Frequency Switching Power Converters

    Master-uppsats, Linköpings universitet/Fysik och elektroteknik; Linköpings universitet/Tekniska högskolan

    Författare :Gagner Anton; Nino Hebib; [2016]
    Nyckelord :FPGA; VHDL; C; Converter; Step-down; Buck; DC DC; Closed-loop; Control; Protocol;

    Sammanfattning : FPGA stands for Field Programmable Gate Array and it is a technology that has been on the rise the last decades. With a decrease in size of the logic elements commercially available products have started to have more built-in functionality in one package and by being reprogrammable makes the system a powerful competitor among its neighbors.
