Journal ArticleDOI
Performance evaluation of OFDM and single-carrier systems using frequency domain equalization and phase modulation
Emad S. Hassan,Xu Zhu,Said E. El-Khamy,Moawad I. Dessouky,Sami A. El-Dolil,Fathi E. Abd El-Samie +5 more
TL;DR: A CPM-based single-carrier frequency domain equalization structure for broadband wireless communication systems that combines the advantages of the low complexity of SC-FDE, in addition to exploiting the channel frequency diversity and the power efficiency of CPM.
Journal ArticleDOI
Peak-to-average power ratio reduction in space-time block coded multi-input multi-output orthogonal frequency division multiplexing systems using a small overhead selective mapping scheme
TL;DR: The authors present a small overhead SLM (s-SLM) scheme for space-time block coded (STBC) MIMO-OFDM systems that improves the system bandwidth efficiency and achieves a significantly lower bit error rate (BER) than the individual SLM and direct SLM schemes.
Journal ArticleDOI
Relay and jammer selection schemes for improving physical layer security in two-way cooperative networks
TL;DR: The obtained results reveal that, despite the presence of cooperating eavesdroppers, the proposed selection schemes are still able to improve both the secrecy rate and the secrecy outage probability of the two-way cooperative networks.
Journal ArticleDOI
Efficient Image Transmission with Multi-Carrier CDMA
TL;DR: Simulation results show that image transmission over wireless channels using the proposed chaotic interleaving approach is much more immune to noise and fading, and adds a degree of encryption to the transmitted data.
Journal ArticleDOI
A Chaotic Interleaving Scheme for the Continuous Phase Modulation Based Single-Carrier Frequency-Domain Equalization System
Emad S. Hassan,Xu Zhu,Said E. El-Khamy,Moawad I. Dessouky,Sami A. El-Dolil,Fathi E. Abd El-Samie +5 more
TL;DR: Simulation results show that the proposed chaotic interleaving scheme can greatly improve the performance of the CPM-SC-FDE system and provides a good trade-off between system performance and bandwidth efficiency.
