Output SPS in pfb_clock_sync

GNU Radio

Hi Everyone,

The generic_demod block in digital has pfb_clock_sync output connected
to
constellation_receiver input.

The pfb_clock_sync has a parameter output SPS. So I assume it represents
the output samples per symbol.

From reading the code in constellation_receiver, I understand that a
symbol
will be computed from a single input. ( Correct me if my understanding
is
wrong )

So If I am correct, setting SPS to a value other than 1, will be
detrimental to demodulation.

So is there any other use of this output SPS?

osps (default=1): The osps is the number of output samples
per symbol. By default, the algorithm produces 1 sample per symbol,
sampled at the exact sample value. This osps value was added to better
work with equalizers, which do a better job of modeling the channel if
they have 2 samps/sym
