3-4 years ago we run fundamental research on geometric information embedding into spatial MIMO processing. That time nobody discuss that in wireless community, yeas there were some topological properties discussion, but nobody look for persistence diagram usage in wireless to identify topological properties and transform them into features. We did a lot of observation here, but didn't find a way to transform this observations into system performance. And nobody was ready to discuss this topic... And ops, unexpected talk from Medhi on #6Gsummitabudhabi ! Sure it is not about channel and MIMO, but about cohomology usage in "semantics", nice to see and maybe time to restart ...
Interesting direction, where we observed many beautiful properties of MIMO channel decomposition/projection. Potentially it can help mathematically proof methodology of "Smart Algorithms" design. May by time is came to understand achieved results 😉

11moNot enough (for me) details. Is this about compression of the feedback related to SU-MIMO channel?
