In my wireless simulation, my BER (bit error rate) statistics when I use the dra_error pipeline stage are different in 9.1 as against later releases. Why is this so, and which value is correct?

Solution

Starting in version 10.0 of the software, the behavior of dra_error is slightly different. Specifically, if the threshhold for errors has been met, dra_error will stop computing errors as a way to speed up the simulation. If an accurate BER value is important, please use dra_error_all_stats for the error pipeline stage. The resulting value will be the one that had been calculated in version 9.1, and it is the correct value. Please read the comments in dra_error.ps.c for more details.
