16. Phosphor Thermometry on Surfaces - A Study of its Methodology and its Practical Applications
Sammanfattning : Phosphor Thermometry is a term describing an optical measurement technique for remote temperature sensing. Its working principle is based on the temperature-sensitive emission characteristics of certain ceramic substances termed thermographic phosphors. LÄS MER
17. Laser-Induced Phosphor Thermometry - Feasibility and Precision in Combustion Applications
Sammanfattning : Temperature is one of the most fundamental parameters to be measured in many research disciplines. In combustion science, a thorough knowledge of temperature is essential for improving and optimizing combustion processes. LÄS MER
18. Characterization and Compensation of Hardware Impairments in Transmitters for Wireless Communications
Sammanfattning : Increasing demands for data rate, energy efficiency and reliability in wireless communications have resulted in the introduction of radio frequency (RF) multiple input multiple output (MIMO) transmitters. However, MIMO transmitters suffer from additional crosstalk impairments along with the power amplifier (PA) and I/Q imbalance distortions observed in single input single output (SISO) transmitters.

19. Design of High-Speed Time-Interleaved Delta-Sigma D/A Converters
Sammanfattning : Digital-to-analog (D/A) converters (or DACs) are one the fundamental building blocks of wireless transmitters. In order to support the increasing demand for highdata-ate communication, a large bandwidth is required from the DAC. LÄS MER
20. Study of Six-Port Modulators and Demodulators for High-Speed Data Communications
Sammanfattning : There is an increasing demand for high-speed wireless data communications to support consumers’ need for, among other things, real time streaming of high definition video and fast file transfers. One radio architecture that has a potential to meet the increasing demand for high-speed data communications is a radio technique based on the six-port architecture. LÄS MER
