Various Views on the Trapdoor Channel and an Upper Bound on its Capacity
Tobias Lutz
Two novel views are presented on the trapdoor channel. First, by deriving the underlying iterated function system (IFS), it is shown that the trapdoor channel with input blocks of…
A Constrained Coding Approach to Error-Free Half-Duplex Relay Networks
Frank R. Kschischang, Tobias Lutz
We show that the broadcast capacity of an infinite-depth tree-structured network of error-free half-duplex-constrained relays can be achieved using constrained coding at the source…
Capacity for Half-Duplex Line Networks with Two Sources
Tobias Lutz, Gerhard Kramer, Christoph Hausl
The focus is on noise-free half-duplex line networks with two sources where the first node and either the second node or the second-last node in the cascade act as sources. In both…
Bits Through Deterministic Relay Cascades with Half-Duplex Constraint
Tobias Lutz, Christoph Hausl, Ralf Kötter
Consider a relay cascade, i.e. a network where a source node, a sink node and a certain number of intermediate source/relay nodes are arranged on a line and where adjacent node pai…
Coding Strategies for Noise-Free Relay Cascades with Half-Duplex Constraint
Tobias Lutz, Christoph Hausl, Ralf Kötter
Two types of noise-free relay cascades are investigated. Networks where a source communicates with a distant receiver via a cascade of half-duplex constrained relays, and networks…
