An efficient Cholesky Decomposition based multiuser MIMO detection algorithm

摘要

This paper presents an efficient multiuser Multiple Input Multiple Output (MU-MIMO) detection algorithm. It introduces Cholesky Decomposition (CLD) and deploys Successive Interference Cancellation (SIC) detection. This study reveals that the proposed algorithm delivers equivalent performance to the QR Decomposition (QRD) based detection algorithm, with adequately lower complexity. As well, the CLD based detection algorithm can be straightforwardly adapted to other QRD based algorithm variants to reduce the computational effort.
