Re: [Discuss-gnuradio] how to change the GRC block shape , size and background of GRC window

[bjoernm]

Hi,

I'm using the UCLA ZigBee PHY by Thomas Schmid, with the benchmark  
example from gnuradio.

Now I need the signal power of each received packet (at the receiver).  
For the signal power computation:

P_S = sum ( all samples squared ) divided by number of samples

but the problem is where to fetch these samples, and how to make sure,  
that only samples of the received packet are considered, and no noise...

1. is there a gnuradio block/function which would already perform this  
task of received signal power computation, or RSSI determination,  
which I could use/edit for my task?

2. If not, where would be the best spot to capture the received  
samples? As the clock_recovery looks to be too late, and capturing the  
packets earlier makes it hard to distinguish between noise and  
received signal, as no clock recovery nor packet detection is  
performed, yet.

I'd appreciate any help, thanks in advanced!
