Centralized RAN for Future Low-Power Wide-Area Networks: A LoRa Case Study
Joachim Tapparel, Amavi Dossa, El Mehdi Amhoud +1
In recent years, low-power wide-area network (LPWAN) technologies have gained significant traction as a connectivity option for Internet of Things (IoT) applications. While these n…
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…
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…
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…
