A hybrid access method for broadcasting of safety messages in IEEE 802.11p VANETs

open access: yesEURASIP Journal on Wireless Communications and Networking, 2021
Vehicular Ad-hoc Networks (VANETs) can improve the road safety by transmitting safety-critical messages such as beacons and emergency messages. IEEE 802.11p VANETs have adopted the carrier sense multiple access with collision avoidance (CSMA/CA ...

Code design for MIMO broadcast channels [PDF]

open access: yesIEEE Transactions on Communications, 2006
Recent information-theoretic results show the optimality of dirty-paper coding (DPC) in achieving the full capacity region of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC). This paper presents a DPC based code design for BCs.

The State-Dependent Semideterministic Broadcast Channel [PDF]

open access: yesIEEE Transactions on Information Theory, 2012
We derive the capacity region of the state-dependent semideterministic broadcast channel with noncausal state-information at the transmitter. One of the two outputs of this channel is a deterministic function of the channel input and the channel state, and the state is assumed to be known noncausally to the transmitter but not to the receivers. We show

Excitonic Anisotropy in Single‐Crystalline 2D Silver Phenylchalcogenides

open access: yesAdvanced Optical Materials, EarlyView.
Using a combination of ab initio theory and optical micro‐spectroscopy, in‐plane anisotropy of multiple delocalized excitons in 2D silver phenylchalcogenides (AgEPh; E = S, Se, Te) is predicted and characterized. Cryogenic reflectance micro‐spectroscopy further reveals the fine structure of excitonic bands in AgSePh.
