Glass fracture surface energy calculated from crystal structure and bond-energy data
Marco Holzer, Tina Waurischk, Janine George +2
We present a novel method to predict the fracture surface energy, γ, of isochemically crystallizing silicate glasses using readily available crystallographic structure data of thei…
Scalable and Energy-Efficient Millimeter Massive MIMO Architectures: Reflect-Array and Transmit-Array Antennas
Vahid Jamali, Antonia M. Tulino, Georg Fischer +2
Hybrid analog-digital architectures are considered as promising candidates for implementing millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems since the…
On Robustness of Massive MIMO Systems Against Passive Eavesdropping under Antenna Selection
Ali Bereyhi, Saba Asaad, Ralf R. Müller +2
In massive MIMO wiretap settings, the base station can significantly suppress eavesdroppers by narrow beamforming toward legitimate terminals. Numerical investigations show that by…
RSB Decoupling Property of MAP Estimators
Ali Bereyhi, Ralf R. Müller, Hermann Schulz-Baldes
The large-system decoupling property of a MAP estimator is studied when it estimates the i.i.d. vector from the observation $\boldsymbol{y}=\mathbf{A}\boldsymbol{x…
Robust Pilot Decontamination Based on Joint Angle and Power Domain Discrimination
Haifan Yin, Laura Cottatellucci, David Gesbert +2
We address the problem of noise and interference corrupted channel estimation in massive MIMO systems. Interference, which originates from pilot reuse (or contamination), can in pr…
On Optimum Asymptotic Multiuser Efficiency of Randomly Spread CDMA
Mohammad Ali Sedaghat, Ralf Müller, Farokh Marvasti
We extend the result by Tse and Verdú on the optimum asymptotic multiuser efficiency of randomly spread CDMA with Binary Phase Shift Keying (BPSK) input. Random Gaussian and random…
Blind pilot decontamination
Ralf Müller, Laura Cottatellucci, Mikko Vehkaperä
A subspace projection to improve channel estimation in massive multi-antenna systems is proposed and analyzed. Together with power-controlled hand-off, it can mitigate the pilot co…
