Full duplex prototype of OFDM on GNURadio and USRPs [PDF]

2014 IEEE Radio and Wireless Symposium (RWS), 2014
Full-duplex is a technology in telecommunication domain that can perform transmitting and receiving at the same time and in the same frequency band. The major obstacle of full-duplex is the self-interference (SI). Some previous works have focused on the SI cancellation in radio frequency (RF), and generally on a narrowband signal model.

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

Radio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

Spatio‐Temporal cGAN Based Channel Estimation for Low‐Altitude Integrated Sensing and Communication Systems

Electronics Letters, Volume 62, Issue 1, January/December 2026.
Reliable channel estimation in low‐altitude ISAC is challenged by UAV‐induced fast‐varying and non‐stationary channels. We present an ST‐cGAN framework that jointly models spatial and temporal features under conditional adversarial learning, achieving superior accuracy and robustness compared with conventional and deep learning baselines.
