Channel Extrapolation in FDD Massive MIMO: Theoretical Analysis and Numerical Validation
François Rottenberg, Rui Wang, Jianzhong Zhang +1
Downlink channel estimation in massive MIMO systems is well known to generate a large overhead in frequency division duplex (FDD) mode as the amount of training generally scales wi…
Enable Super-resolution Parameter Estimation for Mm-wave Channel Sounding
Rui Wang, C. Umit Bas, Zihang Cheng +14
This paper investigates the capability of millimeter-wave (mmWave) channel sounders with phased arrays to perform super-resolution parameter estimation, i.e., determine the paramet…
On channel sounding with switched arrays in fast time-varying channels
Rui Wang, Olivier Renaudin, C. Umit Bas +2
Time-division multiplexed (TDM) channel sounders, in which a single RF chain is connected sequentially via an electronic switch to different elements of an array, are widely used f…
28 GHz Microcell Measurement Campaign for Residential Environment
C. Umit Bas, Rui Wang, Seun Sangodoyin +5
This paper presents results from the (to our knowledge) first double-directionally resolved measurement campaign at mm-wave frequencies in a suburban microcell. The measurements ar…
Dynamic Double Directional Propagation Channel Measurements at 28 GHz
C. Umit Bas, Rui Wang, Seun Sangodoyin +5
This paper presents results from the (to our knowledge) first dynamic double-directionally resolved measurement campaign at mm-wave frequencies for an outdoor microcellular scenari…
Outdoor to Indoor Penetration Loss at 28 GHz for Fixed Wireless Access
C. Umit Bas, Rui Wang, Thomas Choi +5
This paper present the results from a 28 GHz channel sounding campaign performed to investigate the effects of outdoor to indoor penetration on the wireless propagation channel cha…
