Phase retrieval from low-rate samples
Volker Pohl, Fanny Yang, Holger Boche
The paper considers the phase retrieval problem in N-dimensional complex vector spaces. It provides two sets of deterministic measurement vectors which guarantee signal recovery fo…
Nomographic Functions: Efficient Computation in Clustered Gaussian Sensor Networks
Mario Goldenbaum, Holger Boche, Sławomir Stańczak
In this paper, a clustered wireless sensor network is considered that is modeled as a set of coupled Gaussian multiple-access channels. The objective of the network is not to recon…
Classical-Quantum Arbitrarily Varying Wiretap Channel: Ahlswede dichotomy, Positivity, Resources, Super Activation
Holger Boche, Minglai Cai, Christian Deppe +1
We establish Ahlswede dichotomy for arbitrarily varying classical-quantum wiretap channels. This means that either the deterministic secrecy capacity of an arbitrarily varying clas…
Phaseless Signal Recovery in Infinite Dimensional Spaces using Structured Modulations
Volker Pohl, Fanny Yang, Holger Boche
This paper considers the recovery of continuous signals in infinite dimensional spaces from the magnitude of their frequency samples. It proposes a sampling scheme which involves a…
Phase Retrieval via Structured Modulations in Paley-Wiener Spaces
Fanny Yang, Volker Pohl, Holger Boche
This paper considers the recovery of continuous time signals from the magnitude of its samples. It uses a combination of structured modulation and oversampling and provides suffici…
Secrecy capacities of compound quantum wiretap channels and applications
Holger Boche, Minglai Cai, Ning Cai +1
We determine the secrecy capacity of the compound channel with quantum wiretapper and channel state information at the transmitter. Moreover, we derive a lower bound on the secrecy…
