2012-01-02pfb: bug fix for ccf version of the PFB clock sync to handle the d_osps ↵Tom Rondeau
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). This commit also changes the number of samples needed in the QA code for the constellation receiver for a faster test.
2012-01-01scheduler: access to set max noutput_items in start method through Python.Tom Rondeau
2012-01-01scheduler: first attempt at being able to set an upper limit on the ↵Tom Rondeau
noutput_items for all blocks in a flowgraph.

2012-01-01pfb: bug fix for ccf version of the PFB clock sync to handle the d_osps ↵Tom Rondeau
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). This commit also changes the number of samples needed in the QA code for the constellation receiver for a faster test.
2012-01-01pfb: updated and hopefully better documentation of the PFB clock sync blocks.Tom Rondeau

2011-12-30gr: sync the filesystem before python can parse doxygenJosh Blum
2011-12-30cmake: added swig version checkJosh Blum
2011-12-30digital: somewhat strange buy necessary fix for autotools build with guile.Tom Rondeau
2011-12-30digital: added tag_nsamples placeholder into SNR probe block.Tom Rondeau
The intent of this block is to be able to pass messages containing the SNR at a set number of samples.
2011-12-30digital: adding SNR nsamples set/get functions in swig i file.Tom Rondeau
2011-12-30digital: fixed documentation of parameters.Tom Rondeau
2011-12-30digital: update to qa and example code for new constructor with tag_nsamples ↵Tom Rondeau
arg.
2011-12-30digital: the SNR estimator block now issues a tag with the SNR (key = ↵Tom Rondeau
'snr'). The number of samples between when the tag is sent is set in the constructor (default = 10000) and can be changed.
2011-12-30digital: snr probe passing just the 0th input stream to SNR estimator.Tom Rondeau
2011-12-30digital: SNR estimators just take a complex vector; not full vector of ↵Tom Rondeau
complex vectors.
2011-12-29digital: added documentation for SNR estimators; made a Doxygen group for ↵Tom Rondeau
them. Also set the alpha value to a default of 0.001; most won't need to change this.
2011-12-29digital: fixed QA code for SNR estimator SVR name change.Tom Rondeau
2011-12-29digital: adding documentation for SNR estimators; added an estimator for ↵Tom Rondeau
M2M4 type that allows the user to set the kurtosis of the signal and noise, if known, to work with non-MPSK and non-AWGN channels (untested). Also, the technique is signal to variation ratio (SVR), not SVN. Couldn't read my own writing.
2011-12-29digital: adding an example program for the SNR estimators with Python code ↵Tom Rondeau
to compare.
2011-12-29digital: QA code for SNR estimators.Tom Rondeau
2011-12-29digital: fixing up blocks to use SNR est classes more appropriately.Tom Rondeau
2011-12-29digital: added a probe (sink) for the new SNR estimators; also fixes up ↵Tom Rondeau
Makefiles and Swig files for SNR est blocks.
2011-12-29digital: using impl SNR estimator classes instead of function pointers.Tom Rondeau
2011-12-29digital: made separate implementation classes for the different SNR estimators.Tom Rondeau
2011-12-23digital: added a class, digital_mpsk_snr_est_cc, that estimates the SNR of ↵Tom Rondeau
an M-ary PSK signal. This block can calculate the SNR using 1 of 4 different methods specified in the block's constructor. They (tend to) trade off accuracy for computational performnace.
2011-12-22core: added accessors to get all settable values of the channel_model objects.Tom Rondeau
2011-12-22core: added accessors to noise_source to get type and amplitude of object.Tom Rondeau
2011-12-22filters: added accessor functions to FFT and FIR filter classes to return ↵Tom Rondeau
vector of taps.
2011-12-22digital: exposed setting FLL loop bandwidth factor in GRC; must have been ↵Tom Rondeau
overlooked initially.

program looks like it's working again.

Bretheim).

2011-12-14grc: the check for pygtk can fail with no X sessionJosh Blum
However, the module will still import and we can perform the version check. This change to the cmake python module checker will make sure that the module was actually imported, even if the act of importing throws. I believe that this change to the checker is acceptable for all other modules.
