Sad and shocking news. I met Vanu in early 2000′s when he gave an inspiring plenary talk on software-defined radio at an IEEE conference.
Pretty cool and inspiring!
Just discovered this paper. pretty cool. microwave perturbations and characterization of optimal detector signals (“matched filter”) and related to the method of least action.
Very cool! related to the lens array concept that we have pioneered in CAP-MIMO! However, this approach is not true beamspace spatial reuse since different beams correspond to different frequencies via an array waveguide (as in optical fiber) – so room for improvement!
These optical fibers connect to a lens, which can be mounted to a ceiling to create an optical wireless network.
