The PAPR Problem in OFDM Transmission: New Directions for a Long-Lasting Problem
Gerhard Wunder, Robert F. H. Fischer, Holger Boche +2
Peak power control for multicarrier communications has been a long-lasting problem in signal processing and communications. However, industry and academia are confronted with new c…
Arbitrarily varying and compound classical-quantum channels and a note on quantum zero-error capacities
Igor Bjelaković, Holger Boche, Gisbert Janßen +1
We consider compound as well as arbitrarily varying classical-quantum channel models. For classical-quantum compound channels, we give an elementary proof of the direct part of the…
Capacity Results for Arbitrarily Varying Wiretap Channels
Igor Bjelaković, Holger Boche, Jochen Sommerfeld
In this work the arbitrarily varying wiretap channel AVWC is studied. We derive a lower bound on the random code secrecy capacity for the average error criterion and the strong sec…
Strong Secrecy for Multiple Access Channels
Moritz Wiese, Holger Boche
We show strongly secret achievable rate regions for two different wiretap multiple-access channel coding problems. In the first problem, each encoder has a private message and both…
Expected Supremum of a Random Linear Combination of Shifted Kernels
Holger Boche, Brendan Farrell, Michel Ledoux +1
We address the expected supremum of a linear combination of shifts of the sinc kernel with random coefficients. When the coefficients are Gaussian, the expected supremum is of orde…
On the Peak-to-Average Power Ratio Reduction Problem for Orthogonal Transmission Schemes
Holger Boche, Brendan Farrell
High peak values of transmission signals in wireless communication systems lead to wasteful energy consumption and out-of-band radiation. However, reducing peak values generally co…
