qam modulation vhdl

Hi.
I've got a little problem with implementing qam modulator-demodulator model.
First question is: do I have to implement FIR filter in both blocks or can I skip it (if it's easier) ?
Second: How to synchronize modulator & demodulator?

I'm creating this model in vhdl (quartusII). Maybe someone already did it and could share his experience.
Thank You for any advice.
