1. Spatial diversity receivers for base station antenna arrays
Sammanfattning : .... LÄS MER
2. Base Station Coordination in Multicell MIMO Networks
Sammanfattning : The use of multi-antenna technology, also referred to as multiple-input multipleoutput (MIMO), has been shown to improve both the achievable data rates and the link reliability in single-cell wireless systems without a need for extra power or bandwidth. The promised gains of MIMO techniques are, however, severely degraded in a multicell environment due to the presence of intercell interference,especially for users at the cell edge. LÄS MER
3. Direction finding, beamforming and mutual coupling in base station antenna arrays
Sammanfattning : .... LÄS MER
4. GaN HEMT Low Noise Amplifiers for Radio Base Station Receivers
Sammanfattning : Gallium nitride (GaN) high electron mobility transistor (HEMT) has been introduced as the technology of choice for high power microwave applications due to its material properties including high saturation electron velocity and breakdown field together with excellent thermal conductivity and robustness.It is also a promising candidate for receiver front-ends in the radio base station(RBS) where low noise figure and high linearity are key issues for low noiseamplifier (LNA) design.

5. High-End Performance with Low-End Hardware : Analysis of Massive MIMO Base Station Transceivers
Sammanfattning : Massive MIMO (multiple-input–multiple-output) is a multi-antenna technology for cellular wireless communication, where the base station uses a large number of individually controllable antennas to multiplex users spatially. This technology can provide a high spectral efficiency. LÄS MER
