If the packets have a preamble, there's a block called correlate_and_sync
which should do what you want, although it has some issues. See a thread I
started a few days ago about that...

Mike,
Let's call short bursts of data packets (because that’s really what they
are). In packet transmissions, there are a few ways of ensuring that the
synchronizers have enough time to lock up. The easiest way for you to go
about this, is adding a packet header that carries no information, such a
I have an application that needs to decode short bursts of DBPSK data
(which I am not generating myself). The problem I am having is that
the standard PSK Demod blocks don't lock up in time to correctly
decode the first few flags in the packetised data, which means I
generally lose the first packet
After way to much searching ... under Anisochronous modulation, there is
something called Digital Pulse Interval Width Modulation (DPIWM).

Seems like as good a name as any.

I though NRZI had a constant symbol rate. I would expect 011101001 in

Hey Mike,

A friend recently showed me an OOK modulation that I had never seen
before, and I'm wondering if anyone knows a name for this scheme.
It is PWM where both the on periods and off periods carry data in their
durations.
In the example we observed, an on or off period with a duration of two
units rep

Hi Vishwanatha,
the generated python is bogus; the "-->line31...<--" should not
be there. This indicates that there is something wrong with your GRC XML

Hi..
I crated a block named 'costas_loop_cc'. but when I connect to test this
block with NULL sink and NULL Source, shows the error like this:
