Spatial Channel Covariance Estimation for Hybrid Architectures Based on Tensor Decompositions
Sungwoo Park, Anum Ali, Nuria González-Prelcic +1
Spatial channel covariance information can replace full instantaneous channel state information for the analog precoder design in hybrid analog/digital architectures. Obtaining spa…
Spatial Channel Covariance Estimation for the Hybrid MIMO Architecture: A Compressive Sensing Based Approach
Sungwoo Park, Robert W. Heath
Spatial channel covariance information can replace full knowledge of the entire channel matrix for designing analog precoders in hybrid multiple-input-multiple-output (MIMO) archit…
Optimal User Loading in Massive MIMO Systems with Regularized Zero Forcing Precoding
Sungwoo Park, Jeonghun Park, Ali Yazdan Panah +1
We consider a downlink multiuser multiple-input multiple output (MIMO) system employing regularized zero-forcing (RZF) precoding. We derive the asymptotic signal-to-leakage-plus-no…
Dynamic Subarrays for Hybrid Precoding in Wideband mmWave MIMO Systems
Sungwoo Park, Ahmed Alkhateeb, Robert W. Heath
Hybrid analog/digital precoding architectures can address the trade-off between achievable spectral efficiency and power consumption in large-scale MIMO systems. This makes it a pr…
