On lattice codes for Gaussian interference channels

The usefulness of lattice codes is investigated for two-user Gaussian interference channels (IC). A coding scheme based on the compute-and-forward technique is shown to achieve the capacity region of the Gaussian IC under strong interference. The proposed ...

Approximate Ergodic Capacity of a Class of Fading Two-User Two-Hop Networks

Michael Christoph Gastpar, Chien-Yi Wang

The fading AWGN two-user two-hop network is considered where the channel coefficients are independent and identically distributed (i.i.d.) according to a continuous distribution and vary over time. For a broad class of channel distributions, the ergodic su ...

Cooperative Relaying at Finite SNR-Role of Quantize-Map-and-Forward

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

This paper contributes to the design and analysis of Quantize-Map-and-Forward (QMF) relaying by optimizing its performance for small relay networks. QMF was proved to achieve the capacity of arbitrary networks within a bounded gap, as well as the optimal d ...

Orthomode transducer for dual polarized substrate integrated circuits and antennas

Juan Ramon Mosig, Michael Mattes, Marc Esquius Morote

A complete dual polarized substrate integrated structure is presented. It comprises planar excitation schemes for both orthogonal TE10 and TE01 modes along with an orthomode transducer (OMT) to combine/split them. The whole structure is compact (only 2 lay ...

Wireless Neurosensor for Full-Spectrum Electrophysiology Recordings during Free Behavior

Grégoire Courtine, Hao Li, David Allenson Borton, Yao Lu, Jean François Pierre Laurens

Brain recordings in large animal models and humans typically rely on a tethered connection, which has restricted the spectrum of accessible experimental and clinical applications. To overcome this limitation, we have engineered a compact, lightweight, high ...

Cooperative Relaying at Finite SNR–-Role of Quantize-Map-and-Forward

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

Quantize-Map-and-Forward (QMF) relaying has been shown to achieve the optimal diversity-multiplexing trade-off (DMT) for arbitrary slow fading full-duplex networks as well as for the single-relay half-duplex network. A key reason for the DMT-optimality of ...

On Self-interference Suppression Methods for Low-complexity Full-duplex MIMO

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic, Konstantinos Alexandris

Full-duplex wireless communication offers improved spectral efﬁciency, as well as more efﬁcient relaying and medium access, but requires suppression of self-interference. In this paper we analyze the existing methods for active RF suppression and use the ” ...

Optimizing Quantize-Map-and-Forward in Slow Fading Relay Networks

Christina Fragouli, Ayan Sengupta, I-Hsiang Wang

Quantize-Map-and-Forward (QMF) relaying has been shown to achieve the optimal diversity-multiplexing trade-off (DMT) for the slow fading single-antenna relay channel, regardless of whether the relay is full-duplex or half-duplex. A key reason for the DMT o ...
