Assume that before calculating CMUX —— C*(d1-d0) + d0，we have transferred C,d0,d1 to Galios numbers by ntt. But when it comes to CMUX, we have to decomp tlwesample (d1-d0), which I thought can only be done in int32 field.
So, can we do the decomposition in ntt-transfered field? And what's the actual realization in nufhe for this question?
