A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we introduce a windowing technique, which provides optimal time-frequency containment and maximal adjacent channel interference (ACI) rejection for orthogonal frequency-division multiplexing (OFDM)-based ...
Joint optimization of device to device resource and power allocation based on genetic algorithm
(IEEE-Inst Electrical Electronics Engineers Inc, 2018)
Device-to-device (D2D) communication plays an important role in the next generation of communication systems. Enabling D2D communication decreases latency and expands the coverage of a cell in cellular networks. In addition, ...
Partially overlapping filtered multitone with reconfigurable antennas in uncoordinated networks
(Elsevier Sciences Bv, 2017)
Partially overlapping tones (POT) have recently been offered as a promising solution with the aim of decreasing the interference induced on the users for uncoordinated networks. Since each user causes interference on other ...
OFDM with subcarrier number modulation
(IEEE-Inst Electrical Electronics Engineers Inc, 2018)
A new modulation technique, named orthogonal frequency division multiplexing (OFDM) with subcarrier number modulation, is proposed for efficient data transmission. In this scheme, the information hits are conveyed by ...
On signal space diversity: An adaptive interleaver for enhancing physical layer security in frequency selective fading channels
(Elsevier Science Bv, 2017)
Signal space diversity is a powerful technique that increases reliability of detection over fading channels. In this paper, we explore the ability of this technique to provide secure communication. We enhance the security ...
Thresholds optimization for one-bit feedback multi-user scheduling
(Institute of Electrical and Electronics Engineers Inc., 2018)
We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
DFT-based multi-directions directional modulation
(Institute of Electrical and Electronics Engineers, 2019)
In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ...
High-gain pattern reconfigurable MIMO antenna array for wireless handheld terminals
(The Institute of Electrical and Electronics Engineers, 2016)
The analysis, design, experimental development, and test results of a high-gain pattern reconfigurable antenna array are presented. Unlike traditional phased arrays, the proposed array has a compressed footprint making it ...
A two-antenna single RF front-end DOA estimation system for wireless communications signals
(Institute of Electrical and Electronics Engineers, 2014)
Both adaptive beamforming methods and interference management systems improve the capacity of wireless communications systems, however they may require direction of arrival (DOA) information of signals. On the other hand, ...
OFDM-subcarrier index selection for enhancing security and reliability of 5G URLLC services
(IEEE-Inst Electrical Electronics Engineering Inc., 2017)
An efficient physical layer security technique, referred to as OFDM with subcarrier index selection (OFDM-SIS), is proposed for safeguarding the transmission of OFDM-based waveforms against eavesdropping in 5G and beyond ...
