Dear All,

I was exploring the narrowband benchmark codes, I am not able to figure out
how the header of an incoming packet is read. It appears that the
connections made are:

uhd_receiver->[channel_filter->(demodulator->correlator->framer_sink)]
where framer_sink has the received packet queue. However, the queue_watcher
function is defined so to unmake the payload, which means that the header
has been read apriori. I would like to know in which step the packet header
is read, and how to access the signal processing block that does it.

I need to customize the packet header and add extra processing to the
header decoding block. Any help would be much appreciated.

Thanks and Regards,
Dhrubo
