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. Pavel Schukin.
some qustions about equalizers, timing and carrier recovery
