1. 1. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

   University essay from Umeå universitet/Institutionen för fysik

   Author : Oskar Hellström; [2023]
   Keywords : ;

   Abstract : 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. READ MORE

3. 2. Electromagnetic Compatibility (EMC) test in an Open Area

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Nair Samira; [2023]
   Keywords : EMC; EMC Aircraft; EMC Spacecraft; EMC standard;

   Abstract : 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. READ MORE

5. 4. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

   University essay from Umeå universitet/Institutionen för fysik

   Author : Ossian Kynman; [2023]
   Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

   Abstract : 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. READ MORE

6. 5. Exploiting the Overtones in Online Localization of Sound Sources

   University essay from Lunds universitet/Matematisk statistik

   Author : David Sundström; [2022]
   Keywords : Multi-pitch estimation; localization; block sparsity; sparse recursive least squares; online estimation; ADMM; adaptive dictionary; Mathematics and Statistics;

   Abstract : 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. READ MORE
