A simple angle of arrival estimation system
Badawy, Ahmed; Khattab, Tamer; Trinchero, Daniele; ElFouly, Tarek; Mohamed, Amr ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)We propose a practical, simple and hardware friendly, yet novel and very efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation based system requires a switched beam antenna array ... -
Deep Reinforcement Learning for Efficient Uplink NOMA SWIPT Transmissions
ELSAYED, MOHAMED ABDELHAMID MOHAMED (2021 , Master Thesis)A key rival technology in radio access strategies for next generation cellular communications is non-orthogonal multiple access (NOMA) due to its enhanced performance compared to existing multiple access techniques such ... -
Estimating the number of sources in white Gaussian noise: Simple eigenvalues based approaches
Badawy, Ahmed; Salman, Tara; Elfouly, Tarek; Khattab, Tamer; Mohamed, Amr; Guizani, Mohsen... more authors ... less authors ( Institution of Engineering and Technology , 2017 , Article)Estimating the number of sources is a key task in many array signal processing applications. Conventional algorithms such as Akaike's information criterion (AIC) and minimum description length (MDL) suffer from underestimation ... -
FPGA implementation of DWT EEG data compression for wireless body sensor networks
Elsayed, Mohamed; Badawy, Ahmed; Mahmuddin, Massudi; Elfouly, Tarek; Mohamed, Amr; Abualsaud, Khalid... more authors ... less authors ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Wireless body sensor networks (WBSN) provide an appreciable aid to patients who require continuous care and monitoring. One key application of WBSN is mobile health (mHealth) for continuous patient monitoring, acquiring ... -
On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
Badawy, Ahmed; Khattab, Tamer; Elfouly, Tarek; Chiasserini, Carla-Fabiana; Trinchero, Daniele ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In cognitive radio networks, secondary users (SUs) utilize the unused spectrum slots in the assigned band for the primary users (PUs). Conventional cognitive radio networks operate in half-duplex (HD) mode. Recently, ... -
Performance of eigenvalue based spectrum sensing in full-duplex cognitive radio networks
Badawy, Ahmed; Elfouly, Tarek; Khattab, Tamer; Chiasserini, Carla-Fabiana; Trinchero, Daniele ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)Spectrum sensing is a key component in any cognitive radio network. Recently full-duplex communication, i.e., the ability to transmit and receive at the same time at the same frequency, has become feasible. Residual self ... -
