Re: [Discuss-gnuradio] Re: questions on SNR estimation from digital-bert examples

Alex, Yes, for what I'm doing, the optical link will be AWGN. I'm doing direct detection (lots of photons) with a uncooled Si photodiode. Thanks for the feedback. I have limited (none) experience with realtime receivers so it's hard for me to judge how much loss I'll experience from the realtime s

Here's an image of the BER vs. SNR plot plotted along with the theoretical BPSK line. http://www.flickr.com/photos/gallamine/5580109538/ You can see that the experimental data is 3-4 dB greater than the theoretical BPSK values. My setup looks l
