Estimation of Channel State Information (CSI) in Cell-Free Massive MIMO Based on Time of Arrival (ToA)
Cell-free massive multiple input multiple output (MIMO) comprises a large number of distributed single antenna access points (APs) connected to a network controller through backhaul. Each user is served by neighbouring APs simultaneously. Cell-free Massive MIMO provides decent throughput and coverag...
