You are correct, the main of my project was to compare the channel estimation methode by training and pilot signal.
Training signal methode is not bw efficient like in the model.
Pilot signal -> i inserted some pilot on certain subcarriers then interpolated them to have channel response -> this very good for fast fading channel. I havent submitted it yet
This is Gito, sorry for late response about some issues which rise by Shari.
My mail has lot of Bulk, so i rarely check it.
Actually, the problem on the switch_off.jpg etc, might be due to the picture, so it is recommended to delete all switches picture. All switched is used for showing the spectrum and time scope. To show this spectrum and scope, you can find it all inside the block, i forget which block it is.
