Two-Slot Channel Estimation for Analog Network Coding Based on OFDM in a Frequency-Selective Fading Channel
—Recently, broadband analog network coding (ANC) was introduced to utilize high-data rate transmission over the wireless – frequency selective fading – channel. However, ANC ...

Improving wireless physical layer security via cooperating relays
Physical (PHY) layer security approaches for wireless communications can prevent eavesdropping without upper layer data encryption. However, they are hampered by wireless channel c...

Optimal relay functionality for SNR maximization in memoryless relay networks
We explore the SNR-optimal relay functionality in a memoryless relay network, i.e. a network where, during each channel use, the signal transmitted by a relay depends only on the ...
