Scattering Environment Aware Joint Multi-user Channel Estimation and Localization with Spatially Reused Pilots
Kaiyuan Tian, Yani Chi, Yufan Zhou +1
The increasing number of users leads to an increase in pilot overhead, and the limited pilot resources make it challenging to support all users using orthogonal pilots. By fully ca…
