Low-Complexity Soft-Output Signal Detection Based on Gauss-Seidel Method for Uplink Multi-User Large-Scale MIMO Systems
Linglong Dai, Xinyu Gao, Xin Su +3
For uplink large-scale MIMO systems, minimum mean square error (MMSE) algorithm is near-optimal but involves matrix inversion with high complexity. In this paper, we propose to exp…

Spatially correlated channel estimation based on block iterative support detection for large-scale MIMO
Wenqian Shen, Linglong Dai, Zhen Gao +1
Downlink channel estimation with low pilot overhead is an important and challenging problem in large-scale MIMO systems due to the substantially increased MIMO channel dimension. I…
