21. Characterization of MIMO Antennas and Terminals: Measurements in Reverberation Chambers
Sammanfattning : The reverberation chamber (RC) has drawn attention as a multipath emulator over the past decade for both passive and active over-the-air (OTA) tests. The overview of this thesis is given in Chapter 1. LÄS MER
22. Using multiple SIMD architectures for multi-channel radar signal processing
Sammanfattning : .... LÄS MER
23. Multiple Access protocols with smart antennas in multihop Ad hoc rural-area networks
Sammanfattning : .... LÄS MER
24. Performance characterization of compact multiple antenna terminals
Sammanfattning : Co-band multi-antenna implementation in realistic compact user terminals is of great interest to the wireless telecom industry for achieving high data rates. This licentiate thesis focuses on the mechanisms behind the implementation of multiple antennas for diversity and MIMO gains in everyday user terminals. LÄS MER
25. Reconfigurable MEMS Antennas and Coupling Matrix Estimation
Sammanfattning : One of the demands for future wireless communication systems is higher data rates. New applications demand higher data rates and higher data rates give the service providers the possibility to offer new services. To achieve higher data rates the concept of MIMO (Multiple-Input Multiple-Output) systems has emerged. LÄS MER
