Coded Backscattering Communication with LTE Pilots as Ambient Signal

no code implementations20 Feb 2024 Jingyi Liao, Kalle Ruttik, Riku Jantti, Phan-Huy Dinh-Thuy

In this paper, we propose the adoption of the same convolutional coding methodology for backscatter links that is already employed for LTE downlink control signals.

Ambient FSK Backscatter Communications using LTE Cell Specific Reference Signals

no code implementations31 Jan 2023 Jingyi Liao, Xiyu Wang, Kalle Ruttik, Riku Jantti, Phan-Huy Dinh-Thuy

Long Term Evolution (LTE) signal is ubiquitously present in electromagnetic (EM) background environment, which make it an attractive signal source for the ambient backscatter communications (AmBC).

Ambient backscatter communications using LTE cell specific reference signals

no code implementations2 Sep 2022 Kalle Ruttik, Xiyu Wang, Jingyi Liao, Riku Jantti, Phan-Huy Dinh-Thuy

Long Term Evolution (LTE) systems provide ubiquitous coverage for mobile communications, which makes it a promising candidate to be used as a signal source in the ambient backscatter communications.

Revisiting Pretraining for Semi-Supervised Learning in the Low-Label Regime

no code implementations6 May 2022 Xun Xu, Jingyi Liao, Lile Cai, Manh Cuong Nguyen, Kangkang Lu, Wanyue Zhang, Yasin Yazici, Chuan Sheng Foo

Recent studies combined finetuning (FT) from pretrained weights with SSL to mitigate the challenges and claimed superior results in the low-label regime.
