Journal ArticleDOI
Wireless Relay Communications with Unmanned Aerial Vehicles: Performance and Optimization
TL;DR: This paper develops an algorithm for optimizing the performance of the ground-to-relay links through control of the UAV heading angle, and proposes a smart handoff algorithm that updates node and relay assignments as the topology of the network evolves.
Journal ArticleDOI
Models for MIMO propagation channels : a review
Kai Yu,Bjorn Ottersten +1 more
TL;DR: This paper reviews recently published results on multiple input multiple output (MIMO) channel modeling and distinguishes between two main approach approaches.
Journal ArticleDOI
Modeling of wide-band MIMO radio channels based on NLoS indoor measurements
TL;DR: A previously proposed Kronecker-structure-based narrow-band model for nonline-of-sight (NLoS) indoor multiple-input-multiple-output (MIMO) radio channels based on 5.2-GHz indoor MIMO channel measurements is verified and it is shown that the MIMo channel covariance matrix can be well approximated by the Kr onecker product of the covariance matrices.
Proceedings ArticleDOI
Second order statistics of NLOS indoor MIMO channels based on 5.2 GHz measurements
TL;DR: It is shown that for NLOS indoor scenarios, the MIMO channel covariance matrix can be well approximated by a Kronecker product of the covariance matrices describing the correlation at the transmitter and receiver side respectively.
Proceedings ArticleDOI
A wideband statistical model for NLOS indoor MIMO channels
TL;DR: The investigation shows that for non-line-of-sight (NLOS) cases, the average power delay profiles fit the exponentially decaying curve quite well, therefore a simple wideband model for single-input single-output (SISO) proposed in COST259 has been used in the model.
