On quantized compressed sensing with saturated measurements via convex optimization
(
European Signal Processing Conference, EUSIPCO
, 2016 , Conference Paper)
In this paper, we address the problem of sparse signal recovery, from multi-bit scalar quantized compressed sensing measurements, where the saturation issue is taken into account. We propose a convex optimization approach, ...
Achievable Rates of Buffer-Aided Full-Duplex Gaussian Relay Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output Gaussian relay channel. The FD relay still suffers from residual self-interference (RSI) after ...
Power control and RB allocation in cloud radio access networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In the LTE system the fractional power control and the universal frequency reuse have been targeted. The fractional power control approach decreases the inter-cell interference but may impact the throughput. The universal ...
Optimal Group Formation in Dense Wi-Fi Direct Networks for Content Distribution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Wi-Fi Direct enables direct communication between Wi-Fi devices by forming Peer to Peer (P2P) groups. In each P2P group, one device becomes the Group Owner (GO) and serves as an access point (AP) to connect the remaining ...
Integrating variability management in data center networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
Data centers have an important role in supporting cloud computing services (i.e. checking social media, sending emails, video conferencing, .). Hence, data centers topologies design became more important and must be able ...
Securing Untrusted RF-EH Relay Networks Using Cooperative Jamming Signals
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We propose a new scheme to secure a wireless-powered untrusted cooperative-communication network, where a legitimate source node (Alice) transmits her information messages to a legitimate destination node (Bob) through the ...
Green data center networks: A holistic survey and design guidelines
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Data Center Networks (DCNs) are attracting immense interest from the industry, research and academia to keep pace with the increase of Internet services demands. One of the major concerns that draws the attention of ...
Security-Enhanced SC-FDMA Transmissions Using Temporal Artificial-Noise and Secret Key Aided Schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
We investigate the physical-layer security of uplink single-carrier frequency-division multiple-access (SC-FDMA) systems. Multiple users, Alices, send confidential messages to a common legitimate base-station, Bob, in the ...
Impact of the Wireless Network's PHY Security and Reliability on Demand-Side Management Cost in the Smart Grid
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
We investigate the impact of the wireless network's physical layer (PHY) security and reliability on demand-side management operation in the smart grid. We assume that consumers communicate their energy demands with the ...
LaCoDa: Layered connected topology for massive data centers
(
Academic Press
, 2017 , Article)
One of the fundamental challenges of existing data centers is to design a network that interconnects massive number of servers, and therefore providing an efficient and fault-tolerant routing service to upper-layer ...
