On the Effect of Mutual Coupling in One-Bit Spatial Sigma-Delta Massive MIMO Systems
Hessam Pirzadeh, Gonzalo Seco-Granados, A. Lee Swindlehurst +1
The one-bit spatial Sigma-Delta concept has recently been proposed as an approach for achieving low distortion and low power consumption for massive multi-input multi-output system…

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.…

Spectral Efficiency of Mixed-ADC Massive MIMO
Hessam Pirzadeh, A. Lee Swindlehurst
We study the spectral efficiency (SE) of a mixed-ADC massive MIMO system in which K single-antenna users communicate with a base station (BS) equipped with M antennas connected to…
