1. Evaluation of Drone Neutralization Methods using Radio Jamming and Spoofing Techniques
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The usage of drones is steadily increasing as drones are becoming more available and useful to the general public, but drone usage also leads to problems as for example airports have had to shutdown due to drone sightings. It has become clear that a counter-drone system must be in place to neutralize intruding drones. LÄS MER
2. Analytical Calibration Scheme Suitable for Modern Mobile Communication Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modern systems utilize multiple transceiver modules to enhance capacity by directing the energy of the basestation only at the desired directions using beamforming algorithms. To accurately control the beam patterns, the phase and amplitude at each antenna port must be manipulated to follow the desired beam weight response. LÄS MER
3. Characterization of Passive Intermodulation Distortion in MultiBand FDD Radio Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Intermodulation distortion (IMD) is a phenomenon that results in generation of spurious distortion signals when two or more signals of different frequencies pass through a nonlinear system. In general, IMD occurs in active circuits of a radio system, however, passive wireless components such as filters, transmission lines, connectors, antennas, attenuators etc. LÄS MER
4. Area and Power Efficiency of Multiplier-Free Finite Impulse Response Filters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In digital radio systems, a large number of finite impulse response filters are typically used. Due to their nature of operation, such filters require many multiplication operations, leading to great costs in terms of both chip area and power consumption. LÄS MER
5. Analys RadioNy : En studie om utmaningar och möjlighetervid integration av nytt radiosystem
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknikSammanfattning : This thesis has been conducted at the Swedish Defense Materiel Administration (FMV) on the department of mobile command center with supervised by ÅF. FMV Mobile Command centers main task is to integrate communication systems into Swedish Armed Forces (FM) vehicle systems. FMV has conducted a new radio system that will be integrated in FM. LÄS MER
