1. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. LÄS MER
2. Electromagnetic Compatibility (EMC) test in an Open Area
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Electromagnetic compatibility (EMC) is a very important and increasingly relevant technology in use and is closely related to many technologies such as automobiles and aerospace industry technology including aircraft and spacecraft. Achieving electromagnetic compatibility between equipment inside the device is more than necessary to avoid the problem of interference leading to serious problems. LÄS MER
3. Development of a Novel Method for Automotive On-board Transmitter EMC Immunity Testing
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/ElektricitetsläraSammanfattning : As the automotive industry advances through technology integration, components are designed to operate at increasingly higher frequencies. Consequently, there will be an increasing demand for automotive electromagnetic compatibility (EMC) testing. LÄS MER
4. Analysis and Measurement of Key Performance Indicators for MIMO Antennas
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. LÄS MER
5. Exploiting the Overtones in Online Localization of Sound Sources
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Localization of multiple sound sources from a microphone array is a challenging task that has been a research topic for decades. The challenges stem from the diversity of acoustic contexts due to reverberation and disturbances. LÄS MER
