11. Time of Flight Estimation for Radio Network Positioning
Sammanfattning : Trilateration is the mathematical theory of computing the intersection of circles. These circles may be obtained by time of flight (ToF) measurements in radio systems, as well as laser, radar and sonar systems. A first purpose of this thesis is to survey recent efforts in the area and their potential for localization. LÄS MER
12. Advanced Analog MMICs for mm-wave Communication and Remote Sensing in 0.15µm mHEMT Technology
Sammanfattning : Multi-Gigabit per second wireless communication and atmospheric remote sensing for weather forecasts are new applications in the mm-wave frequency spectra. The High Electron Mobility Transistor is an excellent technology for high frequency mm-wave applications. Its low noise and linear performance makes a 0. LÄS MER
13. Microwave and millimeter wave CMOS Characterization, modeling, and design
Sammanfattning : The use of CMOS technologies for microwave and millimeter wave applications has recently been made possible as a result of increased transistor performance. The fT and fmax have, for example, passed 100 GHz at the 130 nm node and 200 GHz at the 65 nm node. LÄS MER
14. On the Antenna-Channel Interactions: A Spherical Vector Wave Expansion Approach
Sammanfattning : The main focus of this thesis is the analysis of the interactions between antennas and channels where electromagnetic fields play a central role. Our goal has been to devise a general framework to enable a clear separation of the properties of the propagation channel from the influence of the antennas at the same time as it provides a common ground for a joint characterization of their properties.

15. PID Controllers Design and Evaluationn
Sammanfattning : PID control has been the most widely spread form of feedback in industry for at least five or six decades. It has very old roots, but prior to the 1930s the development was driven by instrument companies, plant designers and plant operators. Today the interest among academics is large and increasing.
