Free space optical communication channels can transmit high-speed data between sites over the air. We show here that a FSO digital optical communication channel can be re-purposed and used directly ...

I/ATLAS, earlier known as A11pI3Z, is only the third interstellar visitor to be discovered passing through our corner of the ...

Orthogonal time frequency space (OTFS) is a novel waveform that provides a superior performance in doubly-dispersive channels. Since it spreads information symbols across the entire delay-Doppler ...
