Here is a vector whose components are Fourier transforms
of all *N*-1 traces beyond the *i*-th trace, is the spectral matrix of these traces, and is the vector of cross-spectra between the *i*-th trace and all others. All
spectra are for some particular frequency.

I don't know yet how to prove that algorithm (5) does a good job of subtracting interfering signals, but I will now try to demonstrate that this is so using some synthetic examples.
