hello every body
I have a problem n my MATLAB modeling at that system
at the beginning of appendix C the standard says that the sub-carriers around 1800 Hz ,, So, where i must multiply Q-phase by sin() and the I-phase by cos() and then subtract I-Q the result is real number
then add the effect of channel model and noise ,,
so , finally i have a complex signal again ,,
while I want to have a real signal to disconnect the I and Q phase again at the receiver by the sub-carrier again
I don't now what must i do to Model that system ,,, is that right to include the sub-carriers in my model or not including it
if any one can help me in faster way please ...
the standard is available here

my Q problem you can see it at page 90
