Hello to everyone,

I am having some trouble trying to execute one script from Matlab toolbox. You may find the corresponding information here.

I think I still have not clear how this example works. Although I try to modify the 'EsNodB' value in 'commDVBS2WithLDPC.m' script to reach the values that appear in the second plot, I never get even close to them (assuming that the cBER value corresponds to the LDPC BER one...)

In a nutshell, does anyone know what to modify in the script to get the BER values appearing in the plot?

Many thanks in advance, and best regards.

Why do you want to modify the EsNodB values and how do you expect to reach the values in the second plot? Your question is not very clear. Could you please add additional details?
