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…
High-Throughput Flexible Belief Propagation List Decoder for Polar Codes
Yuqing Ren, Yifei Shen, Leyu Zhang +4
Owing to its high parallelism, belief propagation (BP) decoding is highly amenable to high-throughput implementations and thus represents a promising solution for meeting the ultra…
A Sequence Repetition Node-Based Successive Cancellation List Decoder for 5G Polar Codes: Algorithm and Implementation
Yuqing Ren, Andreas Toftegaard Kristensen, Yifei Shen +3
Due to the low-latency and high-reliability requirements of 5G, low-complexity node-based successive cancellation list (SCL) decoding has received considerable attention for use in…
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…
