MadRadar: A Black-Box Physical Layer Attack Framework on mmWave Automotive FMCW Radars

no code implementations27 Nov 2023 David Hunt, Kristen Angell, Zhenzhou Qi, Tingjun Chen, Miroslav Pajic

Frequency modulated continuous wave (FMCW) millimeter-wave (mmWave) radars play a critical role in many of the advanced driver assistance systems (ADAS) featured on today's vehicles.

Fast WDM provisioning with minimal probing: the first field experiments for DC exchanges

no code implementations14 Sep 2023 Hideki Nishizawa, Toru Mano, Thomas Ferreira de Lima, Yue-Kai Huang, Zehao Wang, Wataru Ishida, Masahisa Kawashima, Ezra Ip, Andrea D'Amico, Seiji Okamoto, Takeru Inoue, Kazuya Anazawa, Vittorio Curri, Gil Zussman, Daniel Kilper, Tingjun Chen, Ting Wang, Koji Asahi, Koichi Takasugi

Then, using field fibers deployed in the NSF COSMOS testbed (deployed in an urban area), a Linux-based transmission device software architecture, and coherent transceivers with different optical frequency ranges, modulators, and modulation formats, the fast WDM provisioning of an optical path was completed within 6 minutes (with a Q-factor error of about 0. 7 dB).

Self-Normalizing Neural Network, Enabling One Shot Transfer Learning for Modeling EDFA Wavelength Dependent Gain

no code implementations4 Aug 2023 Agastya Raj, Zehao Wang, Frank Slyne, Tingjun Chen, Dan Kilper, Marco Ruffini

We present a novel ML framework for modeling the wavelength-dependent gain of multiple EDFAs, based on semi-supervised, self-normalizing neural networks, enabling one-shot transfer learning.

Directional Measurements in Urban Street Canyons from Macro Rooftop Sites at 28 GHz for 90% Outdoor Coverage

no code implementations1 Aug 2019 Jinfeng Du, Dmitry Chizhik, Reinaldo A. Valenzuela, Rodolfo Feick, Guillermo Castro, Mauricio Rodriguez, Tingjun Chen, Manav Kohli, Gil Zussman

Coverage in the street directly illuminated by a roof edge antenna is found to suffer an average excess loss of 11 dB relative to free space at 200 m, with empirical slope-intercept fit model representing the data with 7. 1 dB standard deviation.

Open-Access Full-Duplex Wireless in the ORBIT Testbed

1 code implementation9 Jan 2018 Tingjun Chen, Mahmood Baraani Dastjerdi, Guy Farkash, Jin Zhou, Harish Krishnaswamy, Gil Zussman

We provide an FD transceiver baseline program and present two example FD experiments where 90dB and 85dB overall SI cancellation is achieved for a simple waveform and PSK modulated signals across both the RF and digital domains.
