[Discuss-gnuradio] gsm gmsk demodulation

[isaacgerg]

Hi,
  Concerning GSM GMSK demodulation, due to the ISI, I initially thought many
folks were using the Viterbi algorithm on the waveform to demodulate it
properly.  After doing some lit review, I am finding that this is not the
case and that when most folks talk about Viterbi concerning GSM GMSK
demodulation, they are referring to undoing the convolution encoding and not
referring to demodultion in the face of ISI.  Can anyone please confirm
this?

I see many demodulators simply just ignoring the ISI and just demodulating
as if it wasnt present.  It seems they just rely on the convolutional
encoding for error correction and therefore dont need to worry about the
ISI......Is this true?
