Is there a block in gnuradio that would watch stream tags and pad
zeros into the stream when a USRP drops packets. This would allow
other processing blocks to assume that outgoing and incoming IQ
streams are always in sync, which would help in many of the
applications that I’m working with.
Is there some upstream logic that makes some assumptions from the sample
count – rather than using the time stamp?
It should be possible to fill in missing samples using the timestamp
information, so the upstream logic sees zeros rather than gaps. But, I
worry that if something isnt keeping up, inserting more host samples
into the pipeline isnt the answer. That could just make the overflows
worse. Its better to make whatever that upstream logic is, to recover
from the gap.
