This was a surprising one. When set with a the same seed (regardless of value) and amplitude, the noise source (gaussian) seems to have 3 dB higher power when running on E310 vs. an i7 platform.
(GNU Radio commit 8220b79653c6c7999a18fed075bdb1c41bca0613 on i7) (e3xx release 3 from here: http://files.ettus.com/e3xx_images/e3xx-release-3/) This problem came up when running unit tests on modems that check BER vs. Eb/n0. Has anyone come across this before? I'm sure there's a good reason/explanation for this - but I'm too tired to think of it. -John
