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.

Active RIS‐Aided Wideband Self‐Interference Cancellation Method for Full‐Duplex and ISAC Systems

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This letter proposes a broadband self‐interference cancellation (SIC) method based on a 4 × 4 active reconfigurable intelligent surface (RIS) array for full‐duplex (FD) and integrated sensing and communication (ISAC) systems. Measurement results demonstrate that the proposed active RIS‐aided SIC method provides an additional 20 dB of SIC over a 200 MHz
