On the performance of advanced QoS-aware packet scheduling for multiantenna packet radio systems
( IEEE , 2010 , Conference Paper)In this paper, we study and analyze the performance of advanced OFDM packet scheduling techniques with given QoS requirements under the 3GPP UTRAN Long Term Evolution (L TE) framework. Stemming from our previous studies ... -
On the performance of coefficient of variation control charts in Phase I
( John Wiley and Sons Ltd , 2018 , Article)Control charts are mainly carried out in 2 interconnected phases: Phase I (retrospective phase) and Phase II (monitoring phase). Phase I uses a stable historical sample to establish control limits that will be used later ... -
On the Performance of Hadamard Ratio Detector-Based Spectrum Sensing for Cognitive Radios
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)We consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ... -
On the performance of LAP-based multiple-hop RF/FSO systems
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)In this paper, we propose a low-altitude aerial platform (LAP) based relaying system, where two LAPs serve as relays. More specifically, the air-to-ground links are assumed to be radio frequency (RF) channels experiencing ... -
On the Performance of Quickest Detection Spectrum Sensing: The Case of Cumulative Sum
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)Quickest change detection (QCD) is a fundamental problem in many applications. Given a sequence of measurements that exhibits two different distributions around a certain flipping point, the goal is to detect the change ... -
On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ... -
On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
( 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, ... -
On the Performance of Tactical Communication Interception Using Military Full Duplex Radios
