some qustions about equalizers, timing and carrier recovery

Started by Pavel Schukin September 19, 2007
Hello, everybody!
My questions are short: 
1)Can i apply equalizer before timing reovery? Or I should get timing
previously?
2) Are there equalizers which adjust timing?
3) I have signal with dramatic ISI. Can I apply timing recovery if the eye
opening is small?
4)Are there algorithms which get timing sinchronization of baseband GMSK
signal having just I and Q components?
5)Are there algorithms which removes frequency offset and phase shift of
baseband GMSK signal having just I and Q components?
Thank you.
