Hello S. L.:
Short Version:
Yes, you are correct!
Some picky details:
Due to technical limitations, the output timing of the Throttle block is not
perfect (but should be good enough, for most practical use cases). Also, due to
this, the Throttle block may output more than one samples at a
Hello S.L:
That sounds correct to me.
One note, however: the sampling rate in GNU Radio is just a conceptual thing,
and does not determine the 'actual time that GNU Radio takes to generate or
consume the samples', if you do not use hardware sinks/sources (like SDR
sources) and/or throttle

Hi,
I'm using a USRP B200 with a GPS antenna and GPSDO. I'm following the
instructions here https://gnss-sdr.org/conf/ . When I run the $ gnss-sdr
--config_file=./my_GPS_receiver.conf line, it runs then fails with the
following:

Thank you Kyeong,
I am working on a publication paper (personal work) which involves MIMO
stuff. I think I will go with LimeSDR which seems cheaper.
For a 2x2, can we still use Ettus MIMO Cable? If not, how the configuration
plays out? Any links for reading will be much appreciated.
Thank you,
Thank you very much for your responses
So, if for example, I want to simulate 1 second of a cosine wave of 1K, with
sample rate of 32K as the example and I have a very powerful computer the
signal source block (cosine) could generate the 32k samples in 0.5 seconds ,
but the 32K wave samples of
Hello Evariste:
You can use Ettus Research's MIMO cable if you want to connect two USRP
N200/N210s (with same daughterboards) to form a 2x2 MIMO system (see:
https://kb.ettus.com/Synchronization_and_MIMO_Capability_with_USRP_Devices) .
LimeSDR, XTRX, and USRP B210 have 2x2 MIMO capabilities
So, let's really look at what you receive there. What's your antenna?
When you connect a QT GUI time sink, what's (roundabout) your maximum
amplitude coming out of the USRP Source?
Best regards,
Marcus

Hello, I have a question about the real-time operation of gnuradio and the
"stream-to-vector" and FFT modules "
In the example image I have:
variable samp_rate to 32K

Hi,
If you’re happy with receive-only you could have a look at KerberosSDR:
