[Discuss-gnuradio] GMSK midamble template matching

I would like to identify the 26 midamble bits in each burst of GSM (GMSK)
data.  I hear that a lot of ppl use correlation to do this.  However, I am
struggling to understand how this technique could work due to the ISI from
the Gaussian pulse shaping.   It seems that the wavefrom of the 26 midamble
bits is depdented on the data coming before them and thus, template matching
would not work.  There must be something I am missing here. Any help would
be greatly appreciated.  

Thanks in advanced,
