Hello all,
I have found this code for a gnuradio block with one input and two output ports
simulating the alamouti decode stage for an ofdm system.
Inside the code the channel state (h00,h01,h10,h11) is also calculated.

Hey everyone
I hope everyone's doing well. I intend to participate in GSoC 2020. and PFA
the proposal for the same. Potential Mentor for the project is Marcus
Leech, although I had lots of inputs from Sebastian and I would like to
thank him for that.
For any suggestion or advices,please let me know

I figure out that indeed that the ports were not properly labeled.
I've moved the antenna to the second RF and it gave a result:

Hello Akram,
What kind of power levels do you expect, and why?
The observed power level depends on multiple factors, including your
environments, antennas, gain settings, and more. Also, USRPs are not calibrated
spectrum analyzers and the numbers do not mean much (the numbers are relative
to

Hi
Possible mistake:
verify the antenna is connected to the selected Rx port
verify the antenna really have some gain in this low frequecy
range (I had this issue with low cost 900 and 1800 Mhz anennas
which are less efficent than a 20 cm
Dear,
I'm starting with USRP N210/Gnuradio, so my first exercise was to test it
using uhd_fft. Here is the result I'm getting:
uhd_fft --args "addr=192.168.10.2" -A RX2 -s 10e6 -g 10 -f 102e6

It seems to be that the result is not really as expected. In this FM band,
I should
