Synthesis of multivariate stationary series with prescribed marginal distributions and covariance using circulant matrix embeddi
The problem of synthesizing multivariate stationary series Y [n] = (Y1[n], . . . , YP [n])T , n ∈ Z, with prescribed non-Gaussian marginal distributions, and a targeted covarian...
