Try

noise_voltage = self.EbN0_to_noise_voltage(EbN0)/sqrt(2)

the original berawgn.py was already buggy, because it didn't follow a
recent change in the noise power. I've submitted a patch, but it
probably won't be merged before the release cycle is reset (cf
https://github.com/gnuradio/gnuradio/compare/master...mbr0wn:digital/berawgn_fix_noisepower?expand=1).
