Hi Zenghao,
Thank you for your reply. I have few more queries regarding the carrier
sense module in probe_avg_mag_sqrd_c.cc file. It looks like to find the
presence of carrier in air, there is a variable d_unmuted, which is being
checked. This variable is set whenever pre_output_iir variable is m
Sachin,
Sure, here is the related code I use:
# get a probe
alpha = 0.001
thresh = 30
self.probe = gr.probe_avg_mag_sqrd_c(thresh,alpha)
# connect usrp to the probe
self._fg.connect(self.u, self.probe)
# wait until the medium is free
while objDemod1.probe.leve
Hi Zhenghao,
Thank you for your valuable reply. I appreciate it. As per your supplied
information, I will start looking for CSMA code in tunnel.py, though if you
can send me your code, it will be quite helpful too. I hope that using
tunnel.py code and help from you I will be able to get the carrie
Sachin,
I don't know if this is helpful, just sharing my experience.
1. You may want to check tunnel.py, in which there is a CSMA scheme --
Eric told me this a couple of weeks ago.
2. It is possible to do some carrier sensing by ourself. You can just
read the signal from the USRP and compare the
Hi,
As per the current status of GNU Radio, I got to know that there is no MAC
(CSMA) implementation. Therefore I am not sure if I can get the signal from
signal processing blocks of GNU Radio about the carrier sensed by USRP
receiver.
Please help me in this regard.
Till now I am able to locate
