Re: [Discuss-gnuradio] PSD in dBm/Hz

[Activecat]

Dear Sirs,

Thanks for the answers. Let me further elaborate.

I could get what I want using Matlab, via below steps:

1).  Using GRC flowgraph, connect the USRP Source to a File Sink.

2).  Copy the file (says, test02.dat) to a PC running Matlab.

3).  Using Matlab, run these commands:

       a).  c = read_complex_binary('test02.dat')

       b).  figure; periodogram( c(1:100000), [], [], 10e6 )          # samp_rate is 10e6

In this case I am able to get a PSD plot.

The question is, how to produce the PSD plot using only gnuradio (without Matlab) ?

Thank you very much.
