Re: [Discuss-gnuradio] 2 RX and 1 TX channel

[kaleem ahmad]

Thanks Jason,

To make the things simple I have first tried sensing with a single channel
(This code is well known and some where available on this forum or GNURadio
examples), it is working fine. In this code I simply display the maximum
value of each FFT scan. When I have some data source at the frequency which
I have set (2.41GHz at the moment) then I can easily see it.

This code is attached as "sensing_single_RX_channel.py" at the end

Then I changed this code for two RX channels, one one path I kept the same
graph for sensing and the output of other graph is sent to a file. If I
forget the output of file for the time being and focus on other leg of the
graph i.e. spectrum sensing even then my sensed signal is too weak. For
example if with one RX version I was receiving value '75' then now I am
receiving only '10'!!!!!!!!!!!!!!!

This 2 RX channel version is also attached as "sensing_2_RX_channel.py"

Its very easy to run these files on your system.

Can some one help me to find what is the problem.

Thanks
