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…
Training Channel Selection for Learning-based 1-bit Precoding in Massive MU-MIMO
Sitian Li, Andreas Burg, Alexios Balatsoukas-Stimming
Learning-based algorithms have gained great popularity in communications since they often outperform even carefully engineered solutions by learning from training samples. In this…
Band-of-Interest-based Channel Impulse Response Fusion for Breathing Rate Estimation with UWB
Sitian Li, Alexios Balatsoukas-Stimming, Andreas Burg
The channel impulse response (CIR) obtained from the channel estimation step of various wireless systems is a widely used source of information in wireless sensing. Breathing rate…
Single-anchor UWB Localization using Channel Impulse Response Distributions
Sitian Li, Alexios Balatsoukas-Stimming, Andreas Burg
Ultra-wideband (UWB) devices are widely used in indoor localization scenarios. Single-anchor UWB localization shows advantages because of its simple system setup compared to conven…
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…
