Subject: [oc] About FSK

Hi all
Iam building FPGA based FSK demodulator . but i don't want to select any 
frequencies for mark and space ... i want to implement an real application
i thought about FSK caller ID detector , but i have faced a problem that F1 
"1200Hz" & F2 "2200Hz" are not orthogonal so how can i detect the start of 
the symbol period .. or by another word the phase shift in the received 
signal when changing from symbol to symbol  ?
So if you have suggestion for another FSK application or any solution for 
this problem please let me know
Thank you
Haytham
