Low-complexity beamspace channel estimation for wideband millimeter-wave massive MIMO system by Jiafeng QIU

“…Focused on the issue in which the problem of low precision of channel estimation and high implementation complexity in wideband millimeter-wave(mmWave) MIMO with lens antenna array system,a successive support detection(GS-SSD) algorithm based on Gauss-Seidel method was proposed in the traditional support detection scheme.In this algorithm,the assumption of common support was not used,and inspired by the successive interference cancellation.This algorithm decomposed the total channel estimation problem into several channel component.In the meanwhile,the Gauss-Seidel method was used to approximate the matrix inversion with high complexity.Simulations were provided to show that the proposed GS-SSD algorithm could significantly reduce the complex multiplication and achieved high performance compared with successive support detection algorithm.…”

Orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO system by Weiting ZHAO, Dongliang XIA

“…Due to the high cost and power consumption of some mixed signal components at mmWave frequencies,the conventional full digital precoding technique encounters the problem of high hardware complexity.Consequently,the hybrid analog-digital precoding architecture has attracted the attentions from both academy and industry.Based on this,an orthogonal beam codebook based hybrid precoding algorithm for mmWave MIMO systems was proposed,which utilized the orthogonality of beam codebook to design the analog beamforming vector of each radio frequency (RF) chain in parallel.As a result,the large computational complexity of the conventional orthogonal matching pursuit (OMP) algorithm and the hardware complexity could be greatly reduced.…”
