Novel hybrid physical layer security technique in RFID systems
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In this paper, we propose a novel PHY layer security technique in radio frequency identification (RFID) backscatter communications system. In order to protect the RFID tag information confidentiality from the eavesdroppers ... -
On correlation-based channel sensing with IQ imbalance
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)This paper addresses the problem of the detection of the presence of a pre-classified (i.e., pulse shape is known) signals with IQ imbalance considering free-space path-loss. We study the effect of IQ distortion on 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 ...
