Covert Communication with Channel-State Information at the Transmitter
Si-Hyeon Lee, Ligong Wang, Ashish Khisti +1
We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states. Here, "covert" means…
Asynchronous Massive Access and Neighbor Discovery Using OFDMA
Xu Chen, Lina Liu, Dongning Guo +1
The fundamental communication problem in the wireless Internet of Things (IoT) is to discover a massive number of devices and to allow them reliable access to shared channels. Ofte…
Sensor Array Design Through Submodular Optimization
Gal Shulkind, Stefanie Jegelka, Gregory W. Wornell
We consider the problem of far-field sensing by means of a sensor array. Traditional array geometry design techniques are agnostic to prior information about the far-field scene. H…
