Trade-off between complexity and BER performance of a polynomial SVD-based broadband MIMO transceiver [PDF]
, 2010 In this paper we investigate non-linear precoding solutions for the problem of broadband multiple-input multiple output(MIMO) systems. Based on a polynomial singular value decomposition (PSVD) we can decouple a broadband MIMO channel into independent ...
