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…
Stationarity Region of Mm-Wave Channel Based on Outdoor Microcellular Measurements at 28 GHz
R. Wang, C. U. Bas, S. Sangodoyin +4
The stationarity region, i.e., the area in which the statistics of a propagation channel remain constant, is an important measure of the propagation channel, and essential for effi…
A Real-Time Millimeter-Wave Phased Array MIMO Channel Sounder
C. Umit Bas, Rui Wang, Dimitris Psychoudakis +5
In this paper, we present a novel real-time MIMO channel sounder for 28 GHz. Until now, the common practice to investigate the directional characteristics of millimeter-wave channe…
Joint Spatial Division and Multiplexing for mm-Wave Channels
Ansuman Adhikary, Ebrahim Al Safadi, Mathew Samimi +4
Massive MIMO systems are well-suited for mm-Wave communications, as large arrays can be built with reasonable form factors, and the high array gains enable reasonable coverage even…
