espnet.nets.pytorch_backend.frontends.beamformer.get_power_spectral_density_matrix(xs: ComplexTensor, mask: Tensor, normalization=True, eps: float = 1e-15) → ComplexTensor

Return cross-channel power spectral density (PSD) matrix

• Parameters:
  • xs (ComplexTensor) – (…, F, C, T)
  • mask (torch.Tensor) – (…, F, C, T)
  • normalization (bool)
  • eps (float)

Returns : psd (ComplexTensor): (…, F, C, C)
