ComplexBeat: Breathing Rate Estimation from Complex CSI
Sitian Li, Andreas Toftegaard Kristensen, Andreas Burg +1
In this paper, we explore the use of channel state information (CSI) from a WiFi system to estimate the breathing rate of a person in a room. In order to extract WiFi CSI component…
An SDR-Based Monostatic Wi-Fi System with Analog Self-Interference Cancellation for Sensing
Andreas Toftegaard Kristensen, Alexios Balatsoukas-Stimming, Andreas Burg
Wireless sensing offers an alternative to wearables for contactless monitoring of human activity and vital signs. However, most existing systems use bistatic setups, which suffer f…
On the Implementation Complexity of Digital Full-Duplex Self-Interference Cancellation
Andreas Toftegaard Kristensen, Alexios Balatsoukas-Stimming, Andreas Burg
In-band full-duplex systems promise to further increase the throughput of wireless systems, by simultaneously transmitting and receiving on the same frequency band. However, concur…
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…
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…
Advanced Machine Learning Techniques for Self-Interference Cancellation in Full-Duplex Radios
Andreas Toftegaard Kristensen, Andreas Burg, Alexios Balatsoukas-Stimming
In-band full-duplex systems allow for more efficient use of temporal and spectral resources by transmitting and receiving information at the same time and on the same frequency. Ho…
