6. Analytical Approaches to Load Modulation Power Amplifier Design
Sammanfattning : In future mobile communication networks, there will be a shift toward higher carrier frequencies and highly integrated multiple antenna systems. The system performance will largely depend on the available radio frequency (RF) hardware. As such, RF power amplifiers (PAs) with improved performance, e.g. LÄS MER
7. VCSEL Cavity Engineering for High Speed Modulation and Silicon Photonics Integration
Sammanfattning : The GaAs-based vertical-cavity surface-emitting laser (VCSEL) is the standard light source in today's optical interconnects, due to its energy efficiency, low cost, and high speed already at low drive currents. The latest commercial VCSELs operate at data rates of up to 28 Gb/s, but it is expected that higher speeds will be required in the near future. LÄS MER
8. Investigation of modulation techniques for high-speed induction machines
Sammanfattning : .... LÄS MER
9. Physical Layer Techniques for High Frequency Wireline Broadband Systems
Sammanfattning : This thesis collects contributions to wireline and wireless communication systems with an emphasis on multiuser and multicarrier physical layer technology. To deliver increased capacity, modern wireline access systems such as G.fast extend the signal bandwidth up from tens to hundreds of MHz. LÄS MER
10. Generation, Modulation, and Detection of Signals in Microwave Photonic Systems
Sammanfattning : This thesis deals with the use of photonic technology in microwave and millimeter-wave applications. The two major parts of this work have been techniques for transmission and signal generation. LÄS MER
