Performances analysis of SEC based transmit diversity systems with MRC receivers
( IEEE , 2012 , Conference Paper)Switch and Examine combining (SEC) diversity scheme is one of the simplest yet efficient diversity schemes. Earlier in [1] and [2], we proposed sequential power loading algorithm to reduce the average power used at the ... -
Physical layer secrecy performance of multiple antennas transmission with partial legitimate user CSI
( Institution of Engineering and Technology , 2019 , Article)Conventional beamforming transmission techniques can enhance physical layer secrecy performance while requiring the full channel state information (CSI) of legitimate users and even that of eavesdroppers at the transmitter. ... -
Progressive image stitching algorithm for vision based automated inspection
( IEEE Computer Society , 2016 , Conference Paper)The increasing number of skyscrapers along with the large number of tall bridges throughout the world also increases the demand of a robust, automated and remotely controlled health monitoring system for civil architectures. ... -
Secrecy for MIMO wiretap and MIMO broadcast channels with fading eavesdroppers: CSI does not increase the secure DoF
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)We investigate the secure degrees of freedom (SDoF) of the wiretap and the K user Gaussian broadcast channels with multiple antennas at the transmitter, the legitimate receivers and an unknown number of eavesdroppers each ... -
Secrecy outage analysis over random beamforming transmission with user scheduling: Collusion vs. exclusion
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In this letter, we study the interacting effects of the exclusion zone and eavesdropper colluding strategy on the secrecy performance of multiple-antenna transmission system. In particular, a base station (BS) applies ... -
Secrecy Outage Performance of Ground-to-Air Communications with Multiple Aerial Eavesdroppers and Its Deep Learning Evaluation
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In this letter, we study the secure information transmission from a ground base station (GBS) to a legitimate unmanned aerial vehicle (UAV) user, in the presence of multiple UAV eavesdroppers. To enhance the secrecy ... -
Secrecy Performance Analysis of Multi-Antenna NOMA System with AF/DF relaying under External and Internal Eavesdropping Scenarios
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple Access (NOMA) users have the capability of decoding the other paired users sharing the same resource bloc. As a result, NOMA technique ... -
Secure Communications Using Directional Modulation
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Limitations on the wireless communication resources (i.e., time and frequency) introduces the need for another domain that can help communication systems to match the increasing demand on high data transfer rates and quality ... -
Secure multiple-users transmission using multi-path directional modulation
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)This work introduces a physical-layer secure multiple-users communication scheme. Our scheme employs the multi-path nature of the wireless channel to provide a different secure communication link for each of the legitimate ... -
Self-Energized UAV-Assisted scheme for cooperative wireless relay networks
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)Unmanned aerial vehicles (UAVs) have recently been envisaged as an enabling technology of 5G. UAVs act as an intermediate relay node to facilitate uninterrupted, high quality communication between information sources and ... -
SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ... -
The effect of additional statistical side information on multiple antenna spectrum sensing
(2012 , Conference Paper)In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) when some or all parameters are unknown. The Generalized Likelihood Ratio (GLR) test is the convectional method to solve ... -
