well thanks bulx.so now if i have to insert guard interval and do cyclic prefix what do i have to do??copy some of the ouputs(x
's) of the IFFT block(depending upon the guard time calculations)at the beginning and transmit this extended frame serially.is that how it should be done??
I'm not planning on going into analog domain .all the stuff is to be done inside the DSP.So is my transmitter complete after the above process??Means it's time to implement the receiver..
thanks again
