Hi Tiankun,
To add on to what Martin said: In DFE, the channel state H_I on
subcarrier i is updated everytime it receives a new symbol on that
subcarrier. It doesn't
Harold,
I'm not using any protocol. This is just a GNURadio application.
It is important to me to know is there any way to optimize input/output
buffers of blocks to reduce latency as much as possible? Is the GNURadio
able to do so automatically?
Best,
Mostafa

Hello everyone,
Im trying to set the TX Gain of USRP device using the following command

Hi All,
I have updated gnuradio to 3.7.5 recently, and then reconfigrebuild
gr-osmosdr to link its lib against to v3.7.5's gnuradio-runtime.so.
But when I import osmosdr, I got below error
ImportError: libgnuradio-runtime-3.7.4.so.0.0.0: cannot open shared

The total gain setting range, and gain step size are set by the
hardware. In most cases, the
step size is 0.5dB.

In other words, it's the slider that's buggy, not the gain setting.

is it possible to run uhd_fft directly from the IQ data coming over usb from an
rtlsdr stick?
or is this only for use with an ettus usrp device?

If you want to do the equivalent of uhd_fft for non-Ettus devices, just
use osmocom_fft

should I already have that installed due having installed gr-osmosdr or do I
need to get it from somewhere else?
I was thinkinkg of having a go with multimode.py as well, thats your piece of
work i think?

looking at the clock recovery MM code, I wonder if d_omega_relative_limit is a

You need libhackrf.

I just finished doing the same thing for my shiny-new Hackrf.
Here is what worked for me on the same Ubuntu and GNURadio:

Thanks for the info. Can anybody please confirm whether the step size limit
of 0.5 dB is valid for USRP N200?

It's not the underlying motherboard, it's the daughter-cards. I think
all of WBX, SBX and CBX use a step attenuator with 0.5dB step size.
