Individual Channel Estimation in a Diamond Relay Network Using Relay-Assisted Training
International Journal of Digital Multimedia Broadcasting, 2017 We consider the training design and channel estimation in the amplify-and-forward (AF) diamond relay network. Our strategy is to transmit the source training in time-multiplexing (TM) mode while each relay node superimposes its own relay training over ...

Advanced Science, EarlyView.A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.

Advanced Science, EarlyView.Bacterial biofilms form a physicochemical barrier. Their dense network structure and redox homeostasis confer high resistance to antimicrobial treatments and immune‐mediated killing and clearance. In this study, SnSe nanosheets with enzyme‐like properties and piezoelectric catalysis can oscillate to regulate bacterial redox homeostasis and improve the ...

Lower Bounds on the Capacity of the Relay Channel with States at the Source
EURASIP Journal on Wireless Communications and Networking, 2009 We consider a state-dependent three-terminal full-duplex relay channel with the channel states noncausally available at only the source, that is, neither at the relay nor at the destination. This model has application to cooperation over certain wireless
