Multi-Environment based Meta-Learning with CSI Fingerprints for Radio Based Positioning
Anastasios Foliadis, Mario H. Castañeda Garcia, Richard A. Stirling-Gallacher +1
Radio based positioning of a user equipment (UE) based on deep learning (DL) methods using channel state information (CSI) fingerprints have shown promising results. DL models are…
Channel Correlation Diversity in MU-MIMO Systems -- Analysis and Measurements
Harsh Tataria, Seun Sangodoyin, Andreas F. Molisch +4
In multiuser multiple-input multiple-output (MU-MIMO) systems, channel correlation is detrimental to system performance. We demonstrate that widely used, yet overly simplified, cor…
Lower Bound on the Sum-rate of Decremental Beam Selection Algorithm for Beamspace MIMO Systems
Naveed Iqbal, Waqas Ahmad, Christian Schneider +1
In general, the zero-forcing (ZF) precoding suffers from a severe receive signal-to-noise ratio (SNR) degradation in the high interference regime. However, recent evidences from re…
3D MIMO Outdoor-to-Indoor Propagation Channel Measurement
Vinod Kristem, Seun Sangodoyin, C. U. Bas +7
3-dimensional Multiple-Input Multiple-Output (3D MIMO) systems have received great interest recently because of the spatial diversity advantage and capability for full-dimensional…
On the SNR Variability in Noisy Compressed Sensing
Anastasia Lavrenko, Florian Roemer, Giovanni Del Galdo +1
Compressed sensing (CS) is a sampling paradigm that allows to simultaneously measure and compress signals that are sparse or compressible in some domain. The choice of a sensing ma…
Design and Analysis of Compressive Antenna Arrays for Direction of Arrival Estimation
Mohamed Ibrahim, Venkatesh Ramireddy, Anastasia Lavrenko +6
In this paper we investigate the design of compressive antenna arrays for direction of arrival (DOA) estimation that aim to provide a larger aperture with a reduced hardware comple…
A Hybrid Channel Model based on WINNER for Vehicle-to-X Application
Peter Große, Christian Schneider, Gerd Sommerkorn +1
V2V and V2I channel modeling became recently more of interest. To provide realistic radio channels either expensive measurements or complex ray tracing simulations are mostly used.…
Estimation of Radio Channel Parameters in Case of an Unknown Transmitter
Stephan Häfner, Reiner Thomä
This paper investigates the estimation of radio channel parameters from receiver data, whereby the transmitter is fully unknown. We use a multipath model to describe the radio chan…
