Highly Stretchable Eu 3+ ‐ Doped PEBAX Elastomers With Complementary Optical Readouts of Strain and Temperature

ABSTRACT Soft photonic materials capable of maintaining optical functionality under large mechanical deformation are highly desirable for wearable photonics, flexible sensors, optical and mechanically adaptive photonic systems. Here, we report highly stretchable luminescent elast...

A&M based fractional delay and Doppler channel estimation in OTFS

Orthogonal time frequency space (OTFS) modulation is a candidate for low-density high-mobility communication (LDHMC) use case in sixth generation (6G) due to its robustness against Doppler effects. This paper presents a low-complexity channel estimation method based on the A&M fr...
