This paper shows that incorporating double diffusion encoding (DDE) measurements help resolve the degeneracy in the parameter estimation for the Standard Model of diffusion in white matter for a Watson fiber distribution function (ODF). This is also the case for an arbitrary ODF, as was later proved.
