An Efficient Cholesky Decomposition based Multiuser MIMO Detection Algorithm
26 September 2010
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. Study reveals, that proposed algorithm delivers equivalent performance to QR Decomposition (QRD) based detection algorithm, with adequately lower complexity. As well, the CLD based detection algorithm can be straightforwardly transplanted to other QRD based algorithm variants to reduce the computation effort.
