I'm not completely sure but AFAIK the time inversion trick works only with
the linear sine sweep excitation signal, not with MLS. For a linear sine
sweep the inverse filter is the same sweep time inverted. For the MLS
excitation signal you must use either proper deconvolution or the fast
Hadamard transform (which I don't know exactly what it is or how it works
but I'm sure it is used with MLS because it is really fast and relying on
some specific properties of the MLS signal provides the same exact result
of a proper deconvolution).
