Hi,

Have you tried other rates? What's the highest sample rate before overflow
occurs?

Maybe a power squelch block? You can filter out signals that don't meet a
db threshold before they reach your PC.

Hi,
My setup is a USRP N210 receiving from a transmitter sending a few packets
a second. (The packets are decoded with Bloessl's 802.15.4 PHY block if it
matters)
Let's say the transmitter is sending data on frequency f_t.
I set the USRP to receive on f_t plus an offset f_o.
The next block is a

Hi,
I believe the problem with the 'small polyphase channelization application'
that I posted to the list could be related to the polyphase channelizer
block downsampling the channels, and consequently insufficient samples are
making it to the PHY receivers for them to decode packets.
I would

Hi,
What errors have you seen with make?
For an easier way, you might try using a Docker image, which simplified the
installation process for me.
After installing Docker, you only need to download and run an image, which
has the software and all of its dependencies already built.
Here is an

Hi,
I am working on an application to capture IEEE 802.15.4 traffic on multiple
channels simultaneously. (I will mention now that I am new to GNU Radio and
DSP.) I can successfully capture on one channel. I read the 2009 paper
"Multi-Channel IEEE 802.15.4 Packet Capture Using Software Defined
