RF beamforming considering RF characteristics in MIMO system

2010 International Conference on Information and Communication Technology Convergence (ICTC), 2010
We propose the multiple-antenna RF beamforming scheme. The proposed scheme adopts the phase shifters and gain controllers in RF domain to compensate the wireless fading channels which is usually operated on the digital domain in the conventional beamforming scheme.

Digital RF and Digitally-Assisted RF

2011
One of the most important developments in the wireless industry within the last decade was the digitization of RF circuitry. This was in response to the incredible advancements of the mainstream CMOS technology in both processing speed and circuit density, as well as the relentless push to reduce total solution costs through integration of RF, analog ...

Integrated RF-CMOS Transceivers challenge RF Test

2006 IEEE International Test Conference, 2006
The CMOS implementation of RF-transceivers for 2G/3G mobile communication standards allows the integration of base-band and RF functions on a single chip at significantly reduced manufacturing cost. Complex RF circuit architectures are now possible, which could not be realized economically before in a mixed bipolar/CMOS technology. This development not

Microbunching and RF Compression

2010
Velocity bunching (or RF compression) represents a promising technique complementary to magnetic compression to achieve the high peak current required in the linac drivers for FELs. Here we report on recent progress aimed at characterizing the RF compression from the point of view of the microbunching instability.
