Guys, i've finished my basic ofdm model and i'm currently working on
the synchronization & later the modelling of the power line transfer
function...

But i just wanna check out with you guys first whether my spectrum is
correct or not...

This is my model (50kb), the AWGN SNR is set at 30...

And this is my output Tx spectrum, averaged about 50 samples
(50kb)

Notice that i have a deep notch at the 0, its because i have 3 zeros on
both sides of the Fs...

I just want to know have i done it right. Please comment...thx guys...

PS: Does anyone know the sequence for HomepLug's synchronization frame?
 

can you help in finding matlab coding for basic OFDM structure.please if you find it send to me because it is very urgent.
 

Download a thesis reagardin OFDM and its simulation using Matlab from yahoo group telecom_research and join yahoo group ofdmmatlab

Your problems will hopefully be solved
