To understand MLSE equaliser properly, try to read Digital Communications
by John G Proakis, 4th edition.
Read section 10.1.2 to 10.1.3, i.e. from page 601 to 607.
he has also given one example.

I haven't analysed it completely but what you'll want to do to prove
the result is to express the equation in vector form
So, the metric to be maximized can be written as the norm of an L-
M^\tilde[k] = || x - A*h ||^2 where x and h are L*1 vectors and A is
an L*L matrix containing the symbols to be decoded.
Then, use vector algebra to simplify, some of the terms will get
removed because each element of A has magnitude=1 and
you should get the form in equation 6.
