This is one of the first approaches to an LTE Simulink model that was developed in the world, back in 2013. It is based on Turbo Coding, 16-QAM, OFDM and pilots.
You can select the parameters for the Rayleigh Channel and the noise in the AWGN channel, then you can observe the changes in the signal's spectrum and in the constellation. In addition, the BER is obtained.
As I mentioned at first, this is one approach, I would like to develop the model as it is specified in the standard.
There are some global parameters configured for the Turbo code, so you need to run the configuration file in Matlab first, in order to load them.

PLEASE, DON'T FORGET TO REFERENCE THE AUTHOR IF YOU USE THE MODEL IN YOUR WORK. THANKS! ;-)
