Good, well done.

Oh, have you, well done again.

One thing I can see you are porbably doing wrong is that you mean GMSK
and not GSMK. What is A/C? Do you mean analog to digital converter
(ADC)?
The other thing you are doing wrong is missing too many words out of
sentences.
Without wanting to sound cruel, you have to structure a sentence
properly as otherwise people will not be able to answer you as they
will not understand the question.

From the above, and using some information theory error decoding I
assume you mean you are looking for an algorithm to demodulate GMSK
and in your device you have an I-Q data stream coming from your ADC.
Am I right?
I don't really know what you mean you when you say you want to find an
algorithm to do this. I would have thought you suss out the theory
first and then write the code for it. Do you understand the theory
first? If so, say exactly what you want to be answered.
