EM == KALMAN when system and observation are linear.

The AEA DSP2232 demodulator worked as well as it did on UO-14
and other NO DC transmitters because it had a fractionally spaced
linear filter followed by a one tap per symbols DFE.  However,
be advised that this is the higher dimensional equivalent of
"dividing by 0".

There are better approaches


"Viterbi equalizer"

or

EM algorithm.
