Exact SINR analysis of OFDM systems under joint Tx/RX I/Q imbalance
(
IEEE
, 2013 , Conference Paper)
The direct-conversion architecture used for Orthogonal Frequency Division Multiplexing (OFDM) systems suffers from intercarrier interference (ICI) between image subcarriers in each OFDM symbol due to I/Q imbalance between ...
Phase noise mitigation in OFDMA uplink
(
IEEE
, 2014 , Conference Paper)
This paper addresses the problem of the phase noise induced spectral spread in an OFDMA uplink scenario. Accompanied with power differences between the users at the receiver in a multiuser case, the phase noise induced ...
Important complexity reduction of random forest in multi-classification problem
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Algorithm complexity in machine learning problems has been a real concern especially with large-scaled systems. By increasing data dimensionality, a particular emphasis is placed on designing computationally efficient ...
A general framework for the design and analysis of sparse FIR linear equalizers
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Complexity of linear finite-impulse-response (FIR) equalizers is proportional to the square of the number of nonzero taps in the filter. This makes equalization of channels with long impulse responses using either zero-forcing ...
Quasi-sparsest solutions for quantized compressed sensing by graduated-non-convexity based reweighted ?1minimization
(
European Signal Processing Conference, EUSIPCO
, 2016 , Conference Paper)
In this paper, we address the problem of sparse signal recovery from scalar quantized compressed sensing measurements, via optimization. To compensate for compression losses due to dimensionality reduction and quantization, ...
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, ...
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 ...
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 ...
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 ...
A guaranteed performance of a green data center based on the contribution of vital nodes
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In order to satisfy the need for the critical computing resources, many data center architectures proposed to house a huge number of network devices. These devices are used to achieve the highest performance in case of ...
