    • ...circularly symmetric complex Gaussian lattice basis matrices, we find that the complexity distribution of SD is of Pareto-type (i.e., the corresponding tails decrease polynomially) with tail exponent given by . We show that this tail exponent cannot be improved (i.e., increased) by LR including layer-sorting (LS) (e.g., according to the V-BLAST algorithm [15]) as a special case...
    • ...We define LR-based preprocessing (see, e.g., [1]) as applying, prior to the QRD, the transformation , where is an unimodular matrix, i.e., , and . The matrix can, in general, depend on and is obtained, for example, through the LLL algorithm [29], which finds a basis matrix of the lattice that is closer to an orthogonal matrix than . Another important preprocessing technique is LS (e.g., according to the V-BLAST algorithm [15]), which is ...
