Hi All
I am trying to develop a GMSK demodulator.
I have digitised a GMSK modulated RF signal (21.4MHz) and then frequency translated it to zero using a complex NCO, the data is then decimated/filtered.
I believe I now have to perform frequency and phase correction, timing correction and demodulation on the sampled data.
Can any one recommend which order these corrections should be done in, and what methods are best suited to GMSK data.
Thanks.
Best regards
Joe
