Taking advantage of the good cross-correlation characteristic of orthogonal pilot sequences ... In the proposed OPSAD algorithm, the min-max covariance interference (MMCI) pilot assignment algorithm ...

Our proposal offers three key advances: (1) it accommodates moderate to large spatial interference effects; (2) it adapts to different spatial covariance functions; (3) it is computationally efficient ...

where constraints on the maximum absolute correlation coefficient are given. A tight upper bound for the joint covariance matrix is derived on the basis of the individual covariances and the ...

BACKGROUND: Desmosomal gene variants (DGVs) have been associated with a diverse spectrum of phenotypic manifestations within ...

We also looked at correlation trends during periods of rising interest rates, elevated inflation, and economic recessions. One key finding: Higher inflation usually leads to closer links between ...

Although there is essentially no correlation between height and points scored at that level, that doesn't mean height isn't important in basketball.) Hambrick offered another potential explanation.

This study examines 1495 publicly listed companies over the period 2016-2022 to assess whether higher ESG (environmental, social, and governance) scores are associated with greater cash dividend ...
