On the Achievable Rates of OFDM with Common Phase Error Compensation in Phase Noise Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Article)
This paper considers the problem of analytically assessing the maximum achievable rates (capacity) of orthogonal frequency division multiplexing (OFDM) transmissions when the receiver, for complexity reasons, only accounts ...
Sparse Equalizers for OFDM Signals with Insufficient Cyclic Prefix
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Article)
The cyclic prefix (CP) is appended in orthogonal frequency division multiplexing (OFDM) signals to combat inter-symbol interference (ISI) and inter-carrier interference (ICI) induced by the communication channel, which ...
Maximum likelihood detection of precoded SFBC in frequency-selective fading channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
In this paper, we derive the maximum likeli-hood detector (MLD) for precoded space-frequency block coded (SFBC) systems where orthogonal frequency divi-sion multiplexing (OFDM) is incorporated. The obtained results reveal ...
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 ...
Self-interference cancellation using time-domain phase noise estimation in OFDM full-duplex systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
In full-duplex systems, the local oscillator phase noise (PN) problem is one of the bottleneck challenges that may face the self-interference cancellation (SIC) stage especially when orthogonal frequency division multiplexing ...
An efficient reduced complexity PAPR reduction approach for 3GPP LTE system

In wideband communication systems, Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has been proposed as an efficient technique to enhance the link reliability and the spectral efficiency. ...
Secondary users selection and sparse narrow-band interference mitigation in cognitive radio networks
(
Elsevier B.V.
, 2018 , Article)
Spectrum scarcity is a critical problem that may reduce the effectiveness of wireless technologies and services. To address this problem, different spectrum management techniques have been proposed in the literature such ...
Modulation-independent non-data-aided SNR estimator for OFDM signals in nakagami fading channels
(2013 , Conference Paper)
A signal-to-noise ratio estimator for OFDM signals in Nakagami-m fading channels is proposed. This estimator can be used with any signal constellation. It is an envelope-based non-data-aided estimator that makes use of ...
Secure multiple-mode OFDM with index modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Multiple-mode orthogonal frequency division multiplexing with index modulation (MM-OFDM-IM) is a promising IM technique for OFDM systems to improve the spectral efficiency. In this paper, a secure index and data symbol ...
