[Discuss-gnuradio] Measure the power using USRP

[w xd]

Hi,

    I want to measure the power.I'm now transmit the OFDM signal.

    I use the usrp to receive data,and I save it to a file.I read all the data.Then:

I use the formula to calculate the power:

    10*log10(sum(abs(data).^2)/0.001)   dbm

   

    Is it the right way to calculate the power under the ofdm?

    Thanks.

Best Regards,
