Secure Transmission on the Two-Hop Relay Channel With Scaled Compute-and-Forward

Michael Christoph Gastpar, Jasper Goseling

In this paper, we consider communication on a two-hop channel in which a source wants to send information reliably and securely to the destination via a relay. We consider both the untrusted relay case and the external eavesdropper case. In the untrusted r ...

On the energy benefit of compute-and-forward for multiple unicasts

Michael Christoph Gastpar, Jasper Goseling

Compute-and-forward (CF) is a technique which exploits broadcast and superposition in wireless networks. In this paper, the CF energy benefit is studied for networks with unicast sessions and modeled by connected graphs. This benefit is defined as the rati ...

Random Access With Physical-Layer Network Coding

Michael Christoph Gastpar, Jasper Goseling

We consider a physical-layer network coding strategy for the random-access channel, based on compute-and-forward. When packets collide, it is possible to reliably recover a linear combination of the packets at the receiver. Over many rounds of transmission ...

Secure transmission using an untrusted relay with scaled compute-and-forward

Michael Christoph Gastpar, Jasper Goseling

A two-hop channel is considered, in which the source wants to send information to the destination while keeping the information confidential from the relay. A novel lattice chain and compute-and-forward based scheme is proposed in which the destination pro ...

Maximum Throughput Gain of Compute-and-Forward for Multiple Unicast

Michael Christoph Gastpar, Jasper Goseling

Compute-and-Forward (CF), also known as reliable physical layer network coding, is a technique that provides the possibility of exploiting the features of broadcast and superposition in wireless networks. It has been shown that the throughput for multiple ...
