  1. 11. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

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

    Author : Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
    Keywords : Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

    Abstract : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. READ MORE

  3. 12. Antenna measurements of HF antennas using low cost UAVs

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

    Author : Ruimin Ma; Jinting Zhang; [2023]
    Keywords : Antenna; HF; UAV; Radiation Pattern; Antenna; HF; UAV; Strålningsmönster;

    Abstract : High-frequency signal far-field measurement systems usually involve the use of complex and expensive equipment, since the measurements must be made at a distance of multiple wavelengths from the antenna. Helicopter surveyors are commonly utilized. READ MORE

  4. 13. Mobile Traffic Classification and Multi-Cell Base Station Control for Energy-Efficient 5G Networks

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

    Author : Cai Tianzhang; [2023]
    Keywords : ;

    Abstract : The global energy consumption of mobile networks is rapidly increasing due to the exponential growth of mobile network traffic. The advent of next-generation cellular technologies such as fifth-generation (5G) and beyond promises higher network throughput and lower latency but also demands higher power consumption for its denser base station (BS) deployment and more energy-intensive processors.

  5. 14. Multiplexing NFC Antennas : An evaluation of the technique and its limitations

    University essay from Jönköping University/JTH, Avdelningen för datavetenskap

    Author : Viktor Gustafsson; Per Ottosson; [2023]
    Keywords : AAT; BER; DSR; Impedance; Multiplexer; NFC; Wireless Technology;

    Abstract : Introduction This study aims to investigate the possibility of driving multiple NFC antennas with a single NFC-controller by using a multiplexer. An artifact was developed and experiments were conducted in order to evaluate the design choice and in addition, to observe the impact of a multiplexer in an NFC system with respect to the number of successful tag detections, bit error rate (BER), the utilization of automatic antenna tuning (AAT) and the physical distance to the NFC tag.

  6. 15. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    University essay from Uppsala universitet/Signaler och system

    Author : Alexander Söderlund; [2023]
    Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE
