Cell-Free Massive MIMO with Nonorthogonal Pilots for Internet of Things
Shilpa Rao, Alexei Ashikhmin, Hong Yang
We consider Internet of Things (IoT) organized on the principles of cell-free massive MIMO. Since the number of things is very large, orthogonal pilots cannot be assigned to all of…
Massive MIMO Channel Estimation with Low-Resolution Spatial Sigma-Delta ADCs
Shilpa Rao, Gonzalo Seco-Granados, Hessam Pirzadeh +2
We consider channel estimation for an uplink massive multiple-input multiple-output (MIMO) system where the base station (BS) uses an array with low-resolution (1-2 bit) analog-to-…
Spectral Efficiency of One-Bit Sigma-Delta Massive MIMO
Hessam Pirzadeh, Gonzalo Seco-Granados, Shilpa Rao +1
We examine the uplink spectral efficiency of a massive MIMO base station employing a one-bit Sigma-Delta sampling scheme implemented in the spatial rather than the temporal domain.…
