intersymbol interference isi
ERIC COSBY'S code about OFDM covers the data transmission.. some one give it to this guy, i don't have it at this time..
ISI can easily be done by introducing noise of the channel..ERIC COSBY'S code adds AWGN noise but only the real part. he wrote its code.. u can type "help awgn" in matlab editor, and u will have its idea,, by using it u can add REAL and IMAGINARY parts of the noises..
so
in genearal,
SYMBOL DATA + NOISE = RECEIVED DATA
and this RECEIVED data has ISI problem, if the amount of noise is high,,,
