Source Coding with Mismatched Distortion Measures
Urs Niesen, Devavrat Shah, Gregory Wornell
We consider the problem of lossy source coding with a mismatched distortion measure. That is, we investigate what distortion guarantees can be made with respect to distortion measu…
The MIMOME Channel
Ashish Khisti, Gregory Wornell
The MIMOME channel is a Gaussian wiretap channel in which the sender, receiver, and eavesdropper all have multiple antennas. We characterize the secrecy capacity as the saddle-valu…
Secure Transmission with Multiple Antennas: The MISOME Wiretap Channel
Ashish Khisti, Gregory Wornell
The role of multiple antennas for secure communication is investigated within the framework of Wyner's wiretap channel. We characterize the secrecy capacity in terms of generalized…
Optimal Sequential Frame Synchronization
Venkat Chandar, Aslan Tchamkerten, Gregory Wornell
We consider the `one-shot frame synchronization problem' where a decoder wants to locate a sync pattern at the output of a channel on the basis of sequential observations. We assum…
Communication under Strong Asynchronism
Aslan Tchamkerten, Venkat Chandar, Gregory Wornell
We consider asynchronous communication over point-to-point discrete memoryless channels. The transmitter starts sending one block codeword at an instant that is uniformly distribut…
Secure Broadcasting
Ashish Khisti, Aslan Tchamkerten, Gregory Wornell
Wyner's wiretap channel is extended to parallel broadcast channels and fading channels with multiple receivers. In the first part of the paper, we consider the setup of parallel br…
