Adaptive bit-loading in relay-aided cognitive radio network
Siddiqi, Muhammad Zain; Furqan, Haji Muhammad; Jabeen, Tayyaba; Ali, Zain; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)In this work, we consider a joint power allocation and bit loading problem in an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) network. The objective is to maximize the end-to-end rate in a ... -
Cyclic Prefix (CP) jamming against eavesdropping relays in OFDM systems
Solaija, Muhammad Sohaib J.; Madni, Haji Muhammad Furqan Ahmed; Ankaralı, Zekeriyya Esat; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc., 2022)Cooperative communication has been widely used to provide spatial diversity benefits for low-end user equipments, especially in ad hoc and wireless sensor networks. However, the lack of strong authentication mechanisms in ... -
Enhancing physical layer security of OFDM systems using channel shortening
Furqan, Haji Muhammad; Hamamreh, Jehad M.; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2017)This work presents a simple, spectral and power efficient scheme for providing secure OFDM communication system using channel shortening. The basic concept is to utilize a channel shortening technique, whose design is based ... -
FDD massive MIMO downlink channel estimation via selective sparse coding over AOA/AOD cluster dictionaries
Nazzal, Mahmoud; Furqan, Haji Muhammad; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2018)Sparse coding over a redundant dictionary has recently been used as a framework for downlink channel estimation in frequency division duplex massive multiple-input multiple-output antenna systems. This usage allows for ... -
On fair interference management in cognitive radio networks
Musab, Muhammad; Ali, Zain; Furqan, Haji Muhammad; Amanat, Irtiza; Jabeen, Tayyaba; Sidhu, Guftaar Ahmad Sardar (Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, we consider power optimization problem in cognitive radio (CR) networks. The aim is to protect the licensed primary users (PUs) from unequal performance degradation by secondary users (SUs). A min-max ... -
Secure communication via untrusted switchable decode-and-forward relay
Furqan, Haji M.; Hamamreh, Jehad M.; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, a practical power efficient technique is proposed for an untrusted decode-and-forward (DAF) based cooperative communication system to provide secure communication between the source and the destination.
