The DVB-T2 implementation supports T2-Lite, tone reservation PAPR reduction

There are grc blocks that you can use directly after installing gr-dvbt.

I like the approach you take by looking at what real life users will want from

my workings almost never make it to the public, because I always
figure they don't address a problem properly or break too much in
comparison to what they can possibly improve.

Hi, not having access to my setup for now but for the beginning you could try
recording the spectrum with your USRP and then use the file source to decode
the signal offline. There is a script file apps/capture.sh that I usually use
to capture data. You may tweak it for your needs (frequency,
data also as you say.
I am using sampling rate of 1 Mbps instead of 10 Mbps which must be the same
for static transmission. Isn't it?

On older gnuradio releases there was an environment variable to set so that it
will switch to single threaded scheduler. Cannot remember the name, though.

Hi Mitul,
one suggestion regarding the output of the VNA: since you do scattered
parameters calculation, you may want to include also b, Y, h, z (I think you
calculate this) parameters output. Here is an old Agilent app note with
formulas between those parameters in appendix B:

You may want to look at the slow frequency hopping implementation of airprobe

Hi Mark,
the gr-dvbt has a QPSK, QAM-16
and QAM-64 implementation of constellation for both Tx/Rx. The standard
it implements is ETSI 300 744 which is OFDM based in which each
subcarier is modulated using the modulations above.

Hi Abhishek,
When implemented gr-dvbt (https://github.com/BogdanDIA/gr-dvbt) I used VOLK in
many places to speed-up the processing. However, there is a great deal of
speed-up that still need to be achieved on both Tx/Rx in order to lower cpu
cycles consumption so there are a lot of challenges

Since you mentioned this, the code in gr-digital performs channel estimation
base on known pilots. It is in the
./gr-digital/lib/digital_ofdm_frame_acquisition.cc
Channel estimation is based on preamble which contains known pilots each second
carrier. Therefore the unknown carrier channel
. This is probably next step to investigate.
The results so far: moslty learning gnuradio internals, problem is still hidden.

I have an issue that appears in all gnuradio versions I used lately (I started
with 3.3 and last week I updated to latest from git) and I thought I should
post here before allocating the time to look into it by myself.
