Merge branch 'max_noutputs'

pfb: bug fix for ccf version of the PFB clock sync to handle the d_osps parameter better.

The block now holds state between calls to work for the number of output symbols instead of requiring a certain number of available outputs (that may never be satisfied)....

pfb: bug fix for ccf version of the PFB clock sync to handle the d_osps parameter better.

The number of output items is now set based on the d_osps and the check in the work function is not needed (actually, that check was wrong and should never have worked correctly, anyway)....

Fixed stupid mistake in new method.

68e48262 09/30/2011 04:31 pm Tom Rondeau

Added a method to get the current timing rate from the pfb clock sync block.

4f6e8d80 09/01/2011 08:06 pm Tom Rondeau

Fixed the PFB clock sync block when asking for multiple samples per symbol out.

digital: reworking pfb_clock_sync block for better construction of diff taps, more accesors.

605f4a3b 07/30/2011 09:09 pm Tom Rondeau

updating PFB clock sync to use loop bandwidth and damping factor instead of setting gains independently.

781de9ee 05/18/2011 11:12 am Tom Rondeau

filter: Adding a concept of output samples per symbol to the PFB clock recovery alg, mostly so you can pass on 2+ samples per symbol to a follow-on equalizer.

Modify all block factories to use gnuradio::get_initial_sptr.

324971d3 03/07/2010 10:06 pm Eric Blossom

Add check_topology, delete d_diff_filters in dtor, cleanup init and use of
logging output streams.

core: added gr.pfb_clock_sync_fff based on _ccf version, updated example

This splits the rate into a fractional an integer value, which allows the loop to adjust the fractional rate while the integer rate keeps the increments moving properly. Allows the max rate deviation to be independent of the integer rate. Scaling of the differential taps also allows alpha and beta to operate independent of the rate when fractional samples per symbol are used. Slightly more tolerant to large signal values, but they still should be close to +/-1.

2b60291c 10/12/2009 08:36 pm Tom Rondeau
