Spectrum Sensing Under Hardware Constraints
Alexandros-Apostolos A. Boulogeorgos, Nestor D. Chatzidiamantis, George K. Karagiannidis
Direct-conversion radio (DCR) receivers can offer highly integrated low-cost hardware solutions for spectrum sensing in cognitive radio systems. However, DCR receivers are suscepti…
Securing the MIMO Wiretap Channel with Polar Codes and Encryption
Dimitrios S. Karas, Alexandros-Apostolos A. Boulogeorgos, Sotirios K. Mihos +2
Polar codes have been proven to be capacity achieving for any binary-input discrete memoryless channel, while at the same time they can reassure secure and reliable transmission ov…
I/Q-Imbalance Self-Interference Coordination
Alexandros-Apostolos A. Boulogeorgos, Vasileios M. Kapinas, George K. Karagiannidis +1
In this paper, we present a novel low-complexity scheme, which improves the performance of single-antenna multi-carrier communication systems, suffering from in-phase and quadratur…
