A Maximum-Likelihood-based Multi-User LoRa Receiver Implemented in GNU Radio
Mathieu Xhonneux, Joachim Tapparel, Orion Afisiadis +2
LoRa is a popular low-power wide-area network (LPWAN) technology that uses spread-spectrum to achieve long-range connectivity and resilience to noise and interference. For energy e…
On the Advantage of Coherent LoRa Detection in the Presence of Interference
Orion Afisiadis, Sitian Li, Andreas Burg +1
It has been shown that the coherent detection of LoRa signals only provides marginal gains of around 0.7 dB on the additive white Gaussian noise (AWGN) channel. However, ALOHA-base…
Lupulus: A Flexible Hardware Accelerator for Neural Networks
Andreas Toftegaard Kristensen, Robert Giterman, Alexios Balatsoukas-Stimming +1
Neural networks have become indispensable for a wide range of applications, but they suffer from high computational- and memory-requirements, requiring optimizations from the algor…
An Open-Source LoRa Physical Layer Prototype on GNU Radio
Joachim Tapparel, Orion Afisiadis, Paul Mayoraz +2
LoRa is the proprietary physical layer (PHY) of LoRaWAN, which is a popular Internet-of-Things (IoT) protocol enabling low-power devices to communicate over long ranges. A number o…
PAC Codes: Sequential Decoding vs List Decoding
Mohammad Rowshan, Andreas Burg, Emanuele Viterbo
In the Shannon lecture at the 2019 International Symposium on Information Theory (ISIT), Arıkan proposed to employ a one-to-one convolutional transform as a pre-coding step before…
Identification of Non-Linear RF Systems Using Backpropagation
Andreas Toftegaard Kristensen, Andreas Burg, Alexios Balatsoukas-Stimming
In this work, we use deep unfolding to view cascaded non-linear RF systems as model-based neural networks. This view enables the direct use of a wide range of neural network tools…
Hardware Implementation of Neural Self-Interference Cancellation
Yann Kurzo, Andreas Toftegaard Kristensen, Andreas Burg +1
In-band full-duplex systems can transmit and receive information simultaneously on the same frequency band. However, due to the strong self-interference caused by the transmitter t…
