Hi,martin,
if so,how do we focus the data on a FPGA for processing?
We plan to use 4 number of X310 for 8X8MIMO, and now we want to use the
rfnoc framework for real-time signal processing. How do we focus the data
on a x310 for processing?. Because the collected data comes from different
x310.

Hi,
I have some doubts on the interfaces available on noc shell and axi wrapper.
Based on the deep dive slides noc shell provides 3 bidirectional busses:
* Command & response
Looking at the noc_shell code this should be indicated as control source. This
bus seems to be able to send commands t
Hi,
as I said before, I had no chance to access the hardware for some time, but
today I had some time.
First of all: I got the time synchronization working. In addition to setting
the time source and setting an initial time through set_time_unknown_pps it
took some time for me to find out that
Hello
I am trying to receive gsm 1800 band using NI USRP 2954R, but when I am trying
to set the sampling rate of uhd_source in gnuradio to 150 MSPS, it's giving an
error message saying hardware does not support sampling rate above 100MSPS.
Please help!

Try 200MS/s. The FPGA can only decimate integer amounts from the ADC rate,
which is 200MS/s.

Ok I will try that.

I again encourage you to look at rx_multi_samples which shows how to
properly set-up a multi-motherboard configuration.

Hi Dario,
Yes, the deep dive is a bit outdated, but most of the core concepts are
still valid. Originally, next_dst was derived from a register in the user
register address space (usually register 128). However, that was wasteful
of user registers, so that signal was pulled into Noc Shell and set
Hi Jonathon,
Thank you for your feedback. There's one more thing I am missing. I need to
implement closed loop frequency hopping in the sense that my rfnoc block
demodulates a signal, provides demodulated data to host along with timestamp
and host needs to send a timed command to another block t
Dario,
I've been working on a similar requirement. how strict are your timing
needs? For prototyping we were able to get microsecond timing with just a
scheduler implemented in python on an E310. The other major limitation
right now is that RFnoc does not implement the UHD tagging of samples on
th
Hi Tom,
Microseconds would be fine as I just need to align to frequency hopping that
has a scale of milliseconds. For the transmit side I should have no issue given
that the transmit block is going to be a custom rfnoc one and I can set it up
to start on a given vita time with a timed register s
Hello Koyel,
This is a fundamental problem that increasing sample rate takes more
processing power to handle but provides more bandwidth of spectrum. How
wide is the signal you need to process? The general recommendation is that
you sample at 1.25 times your bandwidth. This provides 20% more spect
