Thanks for your help. I reviewed the documents again and also looked at the energy detection example in this archive, which was similar to what I'm trying: http://gnuradio.squarespace.com/storage/examples/ucla2014/02-filters_and_filtering.tar.gz I took the parameters to the 4 channel channelizer i

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 Radi
