Fig. 3From: Deficient-basis-complementary rank-constrained spatial covariance matrix estimation based on multivariate generalized Gaussian distribution for blind speech extractionBehavior of SDR improvements under the babble noise condition. SDR improvements are averaged over six speech sources, four target directions, and 10 parameter-initialization random seeds. The shape parameter \(\rho\) in GGD is set to (a) 2 (Gaussian) and (b) 0.5 (super-Gaussian)Back to article page
