Hi, @Marcus : Yes I have already the formulas ad now trying to implement in C++. The problem I have is I need the output from the "USRP source" as number for instaance and then apply formuas and again show it in time axis. I will go back again to the s first chapter maybe I miss something. @Sylvain : Yes that's true from the "USRP source" I need the value as a dBm or dB. The calibration part will do it after getting the value from the source then I will derive the attenuation from noise within formuals. I already did the link budget need just now to values from the source.
Thank you and best regards Abdeslam *Abdeslam Bourkane* On 1 June 2015 at 08:29, Sylvain Munaut <246...@gmail.com> wrote: > Hi, > > > The problem I have is when using the blocks in gnuradio how to retrieve > the > > signal power > > You mean you want the signal power as a dBm value ? > > Just won't happen ...
