Hi, I was wondering if there's a way to use the channel sounder (gr-sounder) with the XCVR d'boards at 5 GHz. I gave it a try, but the channel impulse responses only popped up +-1s and zeros. Well, I wasn't expecting it to work since the XCVR is not mentioned in the README, but can it be tweaked?
Plus, does anyone have any experience with the sounder they'd share? If so, there's a couple of things I'd be interested to know: - What's a sensible distance for getting useful results without any additional hardware? - Can I tune the amp/gain settings to increase my SNR without distorting the result? - Assume the channel's stationary. In that case, every IR vector should contain the same data (up to some phase shift, probably). I'm figuring I could further increase the SNR by averaging (phase-correctly) over several IRs, right? If anyone has any interesting stories on channel sounding with GR/USRP, I'd be grateful for any info. Cheers, MB -- Dipl.-Ing.
