Impact of Line-of-Sight and Unequal Spatial Correlation on Uplink MU-MIMO Systems
Harsh Tataria, Peter J. Smith, Larry J. Greenstein +2
Closed-form approximations of the expected per-terminal signal-to-interference-plus-noise-ratio (SINR) and ergodic sum spectral efficiency of a multiuser multiple-input multiple-ou…
Practical Interpolation for Spectrum Cartography through Local Path Loss Modeling
Shweta Sagari, Larry Greenstein, Wade Trappe
A fundamental building block for supporting better utilization of radio spectrum involves predicting the impact that an emitter will have at different geographic locations. To this…
EM-Based Channel Estimation from Crowd-Sourced RSSI Samples Corrupted by Noise and Interference
Silvija Kokalj-Filipovic, Larry Greenstein
We propose a method for estimating channel parameters from RSSI measurements and the lost packet count, which can work in the presence of losses due to both interference and signal…
V2V Propagation Modeling with Imperfect RSSI Samples
Silvija Kokalj-Filipovic, Larry Greenstein, Bin Cheng +1
We describe three in-field data collection efforts yielding a large database of RSSI values vs. time or distance from vehicles communicating with each other via DSRC. We show sever…
Using the Physical Layer for Wireless Authentication in Time-Variant Channels
Liang Xiao, Larry Greenstein, Narayan Mandayam +1
The wireless medium contains domain-specific information that can be used to complement and enhance traditional security mechanisms. In this paper we propose ways to exploit the sp…
MIMO-Assisted Channel-Based Authentication in Wireless Networks
Liang Xiao, Larry Greenstein, Narayan Mandayam +1
Multiple-input multiple-output (MIMO) techniques allow for multiplexing and/or diversity gain, and will be widely deployed in future wireless systems. In this paper, we propose a M…
