Abstract: This paper aims to enhance the performance of Multiple-Input-Multiple-Output (MIMO) radar systems by efficiently optimizing the covariance matrix and antenna selection vector to minimize the ...

We draw attention to two problems associated with the use of instrumental variables (IV), the importance of which for empirical work has not been fully appreciated. First, the use of instruments that ...

Abstract: Fluid antenna systems (FAS) achieve spatial diversity through multiple closely spaced antenna ports, but the spatial correlation among these ports complicates accurate performance analysis.

This research evaluates the effect of monetary policy rate and exchange rate on inflation across continents using both Frequentist and Bayesian Generalized Additive Mixed Models (GAMMs). Extending an ...

The distribution of an arbitrary linear combination of Student-t random variables with odd degrees of freedom is derived. An easy method of expressing this distribution as a mixture of t-distributions ...
