We present the computational complexity of linear detection mechanisms based on QR, Cholesky and LDL-decomposition algorithms for different massive MIMO configurations.  ...  MIMO symbol detection is one of the most computationally intensive tasks for a massive MIMO baseband receiver.  ...  An analysis of matrix decomposition algorithms for small-scale MIMO detection can be found in [9] . A comparison of explicit vs. implicit approximate inversion has been provided in [10] .  ...

The QR decomposition (QRD) is an important prerequisite for many different detection algorithms in multipleinput multiple-output (MIMO) wireless communication systems.  ...  The comparison of the implementation results clearly showed superiority of the GR-based VLSI solution in terms of area, processing cycles, and throughput.  ...  The QR decomposition (QRD) is one of the key instruments for MIMO receivers, since numerous MIMO detection algorithms require the QRD of the channel matrix as starting point.  ...
