Radio Channel Measurement and Modeling for GBit WLAN

Responsible:

Topics of Investigation:

• Characterization and modeling of MIMO channels at 5 GHz
  Realistic MIMO channel modeling is a prerequisite for reliable performance evaluation of MIMO transceiver concepts. Known channel modeling approaches are evaluated and compared to available measurement data. Required customizations to the WIGWAM application scenarios are investigated.
• Measurements with a 5 GHz RUSK MIMO channel sounder and data analysis
  The RUSK MIMO channel sounder is used for dedicated measurement campaigns in cooperation with WIGWAM partners. The analysis results provide a solid base for the WIGWAM channel models.
• Specification and simulation of a channel sounder hardware extension
  A novel hardware concept will be developed for future channel measurements at higher frequencies (24, 60 GHz) and higher bandwidths (> 1 GHz). The effects of phase noise, phase stability and non-linearities must be considered with respect to typical channel sounder data analysis algorithms.
• Prototype development of a sounder extension for 24 GHz
  An integrated high frequency semiconductor chip solution (SiGe) will be implemented. The operation as a new front-end for the RUSK channel sounder will be demonstrated in lab experiments.
