    • A Limitation of the Kernel Method for Joint Distributions of Arbitrary Variables 

      Baraniuk, Richard G. (1996-02-01)
      Recently, Cohen has proposed a construction for joint distributions of arbitrary physical quantities, in direct generalization of joint time-frequency representations. Actually this method encompasses two approaches, one based on operator correspondences and one based on weighting kernels. The literature has emphasized the kernel method due to its ...
