Compressive phase retrieval of sparse bandlimited signals
Çağkan Yapar, Volker Pohl, Holger Boche
This contribution proposes a two stage strategy to allow for phase retrieval in state of the art sub-Nyquist sampling schemes for sparse multiband signals. The proposed strategy is…
Strong Divergence for System Approximations
Holger Boche, Ullrich J. Mönich
In this paper we analyze the approximation of stable linear time-invariant systems, like the Hilbert transform, by sampling series for bandlimited functions in the Paley-Wiener spa…
The Arbitrarily Varying Wiretap Channel - Secret Randomness, Stability and Super-Activation
Janis Nötzel, Moritz Wiese, Holger Boche
We define the common randomness assisted capacity of an arbitrarily varying channel (AVWC) when the Eavesdropper is kept ignorant about the common randomness. We prove a multi-lett…
On The Capacity of Broadcast Channels With Degraded Message Sets and Message Cognition Under Different Secrecy Constraints
Ahmed S. Mansour, Rafael F. Schaefer, Holger Boche
This paper considers a three-receiver broadcast channel with degraded message sets and message cognition. The model consists of a common message for all three receivers, a private…
