Transmitter and Receiver Window Designs for Orthogonal Time-Frequency Space Modulation [PDF]
IEEE Transactions on Communications, 2020 In this paper, we investigate the impacts of transmitter and receiver windows on the performance of orthogonal time-frequency space (OTFS) modulation and propose window designs to improve the OTFS channel estimation and data detection performance.

Open Set Wireless Transmitter Authorization: Deep Learning Approaches and Dataset Considerations [PDF]
IEEE Transactions on Cognitive Communications and Networking, 2020 Due to imperfections in transmitters’ hardware, wireless signals can be used to verify their identity in an authorization system. While deep learning was proposed for transmitter identification, existing work has mainly focused on classification among a ...

A high Q piezoelectric resonator as a portable VLF transmitter
Nature Communications, 2019 Very low frequency communication systems (3 kHz–30 kHz) enable applications not feasible at higher frequencies. However, the highest radiation efficiency antennas require size at the scale of the wavelength (here, >1 km), making portable transmitters ...

Chirp-based direct phase modulation of VCSELs for cost-effective transceivers [PDF]
, 2017 A 2.5Gb/s DPSK transmitter based on direct phase modulation of a VCSEL using its own chirp is proposed. The VCSEL, which wavelength is 1539.84nm, has been characterized both static and dynamically.

Covert Communication With Channel-State Information at the Transmitter [PDF]
IEEE Transactions on Information Forensics and Security, 2017 We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states.
