Performance Assessment for Cognitive Cooperative Multiple Relays Network (CCMRN) With Imperfect Channel State Information

Autor: Wafaa Radi, Reem H. Abdel-Hadi, Hesham M. El-Badawy, Salwa H. El-Ramly

Publikováno v: IEEE Access, Vol 6, Pp 44607-44615 (2018)

In the underlay spectrum sharing approach, cognitive radios have limited coverage area to keep interference protection for the licensed users. Multiple cooperative relays have shown benefit for allowing reliable communication with an increase in the

Issue 17
Electronics, Vol 10, Iss 2152, p 2152 (2021)

Polar codes are featured by their low encoding/decoding complexity for symmetric binary input-discrete memoryless channels. Recently, flexible generic Successive Cancellation List (SCL) decoders for polar codes were proposed to provide different thro

Publikováno v: Electronics
Volume 10
Issue 14
Electronics, Vol 10, Iss 1723, p 1723 (2021)

Macro cells’ (MCs) densification with small cells (SCs) is one of the promising solutions to cope with the increasing demand for higher data rates in 5G heterogeneous networks (HetNets). Unfortunately, the interference that arises between these den

Securing digital voice communication using non-autonomous modulated chaotic signal

Autor: Salwa H. El Ramly, Mahmoud F. Abd Elzaher, Yasser Kamal, M. Shalaby

Publikováno v: Journal of Information Security and Applications. 34:243-250

In this paper, we present an encryption approach for voice communication systems based on direct chaotic modulation (non-autonomous modulation), in which voice is injected into one variable of the master system (using either Lorenz chaotic flow or Qi

Spectrum Sensing With Sparsity Estimation For Cognitive Radio Systems

Autor: Jiovana Elia Shouhdy, Salwa H. El Ramly, Bassant Abdelhamid

Publikováno v: MENACOMM

Cognitive Radio (CR) is an important wireless system since it opportunistically utilizes the spectrum via sensing the state of each channel in the environment. The key functional block of CR is the spectrum sensing as it senses the spectrum holes. Re
