Plot BER & SNR of LTE

Hello,

I'm trying to plot BER for various values of SNR for LTE communication system, but I'm facing some difficulties since I'm new with Simulink Matlab. The following link is the mdl. file for LTE

https://github.com/BehindTheSciences/Simulink-LTE-16QAM

Could you please help me with that? or if you have the m. file (Matlab code) for LTE with BER, I will be happy to have it.

Best regards,

Mohammed Al-Hamiri

To obtain the BER values for a LTE channel, refer to the example elaborated upon here. Click on “Try it in MATLAB” to get the M-File. The GUI can be used to visualize the plots of BER against Eb/No.

Alternatively, if you require data from the Simulink model, use a “To Workspace” block and connect to the output port “ber”, set the output variable name, and select an appropriate Save Format. This is elaborated upon here. This exports the BER values to the MATLAB workspace. Use the “plot” function elaborated here to plot the variable that has been exported from Simulink. Change the SNR or Eb/No values in the “AWGN” block for experimentation.

Furthermore, the block prior to the “AWGN” block can be replaced by the “MIMO Fading Channel” block elaborated here.here. Alternatively, you could also use the “SISO Fading Channel” block elaborated here. Select the Rayleigh Distribution for the blocks here. Select the Rayleigh Distribution for the blocks.
