| Near-Field MIMO Measurements & Analysis
A paper describing the joint measurement campaign and analysis of a near-field MIMO wireless communication system undertaken by researchers from Vienna University of Technology and Bristol University was presented at the COST IC1004 meeting in Lyon (3rd to 4th May 2012) by Nikola Gvozdenovic. Nikola’s visit to Bristol in February was supported through the COST Short Term Scientific Mission (STSM) scheme. The STSM enabled the recording of a series of 2 x 2 Ultra Wideband (UWB) MIMO channel responses in the CCR anechoic using a channel sounder kindly provided by Toshiba TREL for a range of transmitter to receiver antenna separations. Post visit, Nikola has been able to estimate the mutual information and eigen structure for 6 different antenna configurations as a function of distance following multiple Skype meetings with Will Thompson, Geoff Hilton and Mark Beach from the CSN research group. These early results will be refined to derive channel capacity by optimizing the mutual information. |

| At this year's IEEE MTT-S International Microwave Symposium in Anaheim, Ca several student competitions were held. Gregor Lasser, member of the Institute of Communications and Radio-Frequency Engineering, entered this contest in the category "ASH Receiver Design". The goal of this design contest was to develop and assemble a receiver based on the ASH (Amplifier-Sequenced Hybrid) concept, preferably with minimum power consumption. Directly at the conference location the receivers of the different participants were tested for power consumption and sensitivity.
Gregor Lasser was awarded the second place for his extreme low-current design. |
