On-the-fly Large-scale Channel-Gain Estimation for Massive Antenna-Array Base Stations
Chenwei Wang, Ozgun Y. Bursalioglu, Haralabos Papadopoulos +1
We propose a novel scheme for estimating the large-scale gains of the channels between user terminals (UTs) and base stations (BSs) in a cellular system. The scheme leverages TDD o…
Fog Massive MIMO: A User-Centric Seamless Hot-Spot Architecture
Ozgun Y. Bursalioglu, Giuseppe Caire, Ratheesh K. Mungara +2
The decoupling of data and control planes, as proposed for 5G networks, will enable the efficient implementation of multitier networks where user equipment (UE) nodes obtain covera…
Efficient C-RAN Random Access for IoT Devices: Learning Links via Recommendation Systems
Ozgun Y. Bursalioglu, Zheda Li, Chenwei Wang +1
We focus on C-RAN random access protocols for IoT devices that yield low-latency high-rate active-device detection in dense networks of large-array remote radio heads. In this cont…
Hybrid Beamforming with Selection for Multi-user Massive MIMO Systems
Vishnu V. Ratnam, Andreas F. Molisch, Ozgun Y. Bursalioglu +1
This work studies a variant of hybrid beamforming, namely, hybrid beamforming with selection (HBwS), as an attractive solution to reduce the hardware cost of multi-user Massive Mul…
A novel alternative to Cloud RAN for throughput densification: Coded pilots and fast user-packet scheduling at remote radio heads
Ozgun Y. Bursalioglu, Chenwei Wang, Haralabos Papadopoulos +1
We consider wireless networks of remote radio heads (RRH) with large antenna-arrays, operated in TDD, with uplink (UL) training and channel-reciprocity based downlink (DL) transmis…
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…
Compressed Sensing-based Pilot Assignment and Reuse for Mobile UEs in mmWave Cellular Systems
Weng Chon Ao, Chenwei Wang, Ozgun Y. Bursalioglu +1
Technologies for mmWave communication are at the forefront of investigations in both industry and academia, as the mmWave band offers the promise of orders of magnitude additional…
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…
User Association and Interference Management in Massive MIMO HetNets
Qiaoyang Ye, Ozgun Y. Bursalioglu, Haralabos C. Papadopoulos +2
Two key traits of 5G cellular networks are much higher base station (BS) densities - especially in the case of low-power BSs - and the use of massive MIMO at these BSs. This paper…
Harmonized Cellular and Distributed Massive MIMO: Load Balancing and Scheduling
Qiaoyang Ye, Ozgun Y. Bursalioglu, Haralabos C. Papadopoulos
Multi-tier networks with large-array base stations (BSs) that are able to operate in the "massive MIMO" regime are envisioned to play a key role in meeting the exploding wireless t…
Joint Source-Channel Coding for Deep-Space Image Transmission using Rateless Codes
Ozgun Y. Bursalioglu, Giuseppe Caire, Dariush Divsalar
A new coding scheme for image transmission over noisy channel is proposed. Similar to standard image compression, the scheme includes a linear transform followed by successive refi…
Joint Source-Channel Coding at the Application Layer for Parallel Gaussian Sources
Ozgun Y. Bursalioglu, Maria Fresia, Giuseppe Caire +1
In this paper the multicasting of independent parallel Gaussian sources over a binary erasure broadcasted channel is considered. Multiresolution embedded quantizer and layered join…
