Hey everyone,
I'm on a USRP doing some prototyping of a simple packet radio. I wanted to ask the best method for detecting bursts. GNU Radio seems to support both a 'probe' e.g.
probe = gr.probe_avg_mag_sqrd_c(thresh,alpha)
detected = probe.unmuted()
from tunnel.py, and a 'file sink burst tagger' e.g.
det = gr.simple_squelch_cc(self.threshold, 0.01)
fsnk = gr.tagged_file_sink(gr.sizeof_gr_complex, self.samp_rate)
from uhd_burst_detector.py. Are these functionally equivalent? Is one better to use than the other?
Thanks,
Rob
