Not directly. However, by operating a normally linear amplifier in

I still don't understand where you want to do this from. That is,
which code would be making the determination that it was time to pause
or unpause the timer.
For instance, a new node enters a bac

A new RSSI value is computed at the host with every new block of
samples. It doesn't use the FPGA value. I suppose there is an

Nope.

Is there any way to get an approximate amount of time that has elapsed
since a timeout has been scheduled? Or better yet, a way to pause a
timer? This is extremely useful for backoff periods in MAC contention
protocols. Where, for instance, the timer is only decremented when the

Hi Eric,
Thank you for your help.
You are right 0.384Hz is nothing to worry about :) I misunderstood the 'm'
Regarding the frequency I finally found where the problem comes from:
After the gmsk modulation (blks2.gmsk_mod) I have to scale the value (for
example by multiplying it by 8000) before s
Hi,
Does anyone have clear idea about how gunradio implements serial to parallel
mapping since 802.11 has 52 channels?
I check the gr_ofdm_mapper_bcv.cc , but still have no idea about it.
In further, I want to apply an array mapping to implement that different
channels use different constellat

Hello
I have a project based on the GNU-radio where I am trying to receive

It works just fine under Windows but I get error when I do exactly the

I have tried both to create an additional endpoint and to use the
