Cache-induced Hierarchical Cooperation in Wireless Device-to-Device Caching Networks
An Liu, Vincent Lau, Giuseppe Caire
We consider a wireless device-to-device (D2D) caching network where n nodes are placed on a regular grid of area A(n). Each node caches L_C*F (coded) bits from a library of size L*…
Directional Training and Fast Sector-based Processing Schemes for mmWave Channels
Zheda Li, Nadisanka Rupasinghe, Ozgun Y. Bursalioglu +3
We consider a single-cell scenario involving a single base station (BS) with a massive array serving multi-antenna terminals in the downlink of a mmWave channel. We present a class…
Tracking of Wideband Multipath Components in a Vehicular Communication Scenario
Kim Mahler, Wilhelm Keusgen, Fredrik Tufvesson +2
A detailed understanding of the dynamic processes of vehicular radio channels is crucial for its realistic modeling. In this paper, we present multipath components (MPCs) tracking…
Measurement-Based Wideband Analysis of Dynamic Multipath Propagation in Vehicular Communication Scenarios
Kim Mahler, Wilhelm Keusgen, Fredrik Tufvesson +2
Realistic propagation modeling requires a detailed understanding and characterization of the radio channel properties. This paper is based on channel sounder measurements with 1 GH…
Low-Complexity Massive MIMO Subspace Estimation and Tracking from Low-Dimensional Projections
Saeid Haghighatshoar, Giuseppe Caire
Massive MIMO is a variant of multiuser MIMO, where the number of antennas at the base-station is large, and generally much larger than the number of spatially multiplexed data…
Secret Key Generation Through a Relay
Kittipong Kittichokechai, Rafael F. Schaefer, Giuseppe Caire
We consider problems of two-user secret key generation through an intermediate relay. Each user observes correlated source sequences and communicates to the relay over rate-limited…
Capacity and Degree-of-Freedom of OFDM Channels with Amplitude Constraint
Saeid Haghighatshoar, Peter Jung, Giuseppe Caire
In this paper, we study the capacity and degree-of-freedom (DoF) scaling for the continuous-time amplitude limited AWGN channels in radio frequency (RF) and intensity modulated opt…
Privacy-Constrained Remote Source Coding
Kittipong Kittichokechai, Giuseppe Caire
We consider the problem of revealing/sharing data in an efficient and secure way via a compact representation. The representation should ensure reliable reconstruction of the desir…
Enhancing the Estimation of mm-Wave Large Array Channels by Exploiting Spatio-Temporal Correlation and Sparse Scattering
Saeid Haghighatshoar, Giuseppe Caire
In order to cope with the large path-loss exponent of mm-Wave channels, a high beamforming gain is needed. This can be achieved with small hardware complexity and high hardware pow…
Wireless Caching: Technical Misconceptions and Business Barriers
Georgios Paschos, Ejder Baştuğ, Ingmar Land +2
Caching is a hot research topic and poised to develop into a key technology for the upcoming 5G wireless networks. The successful implementation of caching techniques however, cruc…
Achieving Large Multiplexing Gain in Distributed Antenna Systems via Cooperation with pCell Technology
Antonio Forenza, Stephen Perlman, Fadi Saibi +3
In this paper we present pCellTM technology, the first commercial-grade wireless system that employs cooperation between distributed transceiver stations to create concurrent data…
RRH based Massive MIMO with "on the Fly" Pilot Contamination Control
Ozgun Y. Bursalioglu, Chenwei Wang, Haralabos Papadopoulos +1
Dense large-scale antenna deployments are one of the most promising technologies for delivering very large throughputs per unit area in the downlink (DL) of cellular networks. We c…
