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: 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.
2011-12-29digital: 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: 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: 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.
2011-12-23digital: 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.
2011-12-05docs: more fixes for generated swig files. This worked before the merge, but ↵Tom Rondeau
this forces the build system to generate these before processing the other swig files.
2011-12-04docs: better install of swig docs .i files since we actually have a variable ↵Tom Rondeau
to take care of it already.
2011-11-30docs: fixing variable for location of header files (SOURCE not BINARY).Tom Rondeau
2011-11-28docs: more appropriate variable to use when setting the include/headers ↵Tom Rondeau
directory.
2011-11-28docs: installing generated _doc.i files under autotools.Tom Rondeau
2011-11-27docs: better use of BUILT_SOURCES so I'm not overriding the standard build ↵Tom Rondeau
instructions for it.
2011-11-27docs: autotools Makefile.am generates empty swig_docs .i files; builds in ↵Tom Rondeau
autotools and cmake. The autotools build does not auto-generate the Python documentation for each block like we do with the cmake build, but the empty .i files are required to build things regardless. The swig_doc.py and doxyxml files are distributed with the autotools build in case someone wants to generate this on their own (see README.doxyxml for how to do this). Only for gnuradio-core and gr-digital currently.

2011-09-01digital: adding CPM C++ hier block, which adds a hier directory to ↵Tom Rondeau
gr-digital. Reworked build system to include this in the libraries and modules built.
2011-08-30digital: fixing a few things left out in conversion to gri_control_loop ↵Tom Rondeau
children.
2011-08-30digital: converted mpsk_receiver to use gri_control_loop parent class. ↵Tom Rondeau
Updated QA code for this, too. Again, had to change the expected data since the loop converges at a different rate; tested by setting alpha and beta to old values and it worked with old data still.
2011-08-30digital: converted FLL block to use gri_control_loop parent class.Tom Rondeau
2011-08-29digital: created a separate DQPSK constellation that does not gray code ↵Tom Rondeau
inside the block. This forces a slower decision making routine but allows differential encoding. Gray coding is done using pre_diff_code.

2011-08-14digital: cleaned up Costas loop code by switching over to the ↵Tom Rondeau
gri_control_loop class to handle the inner loop. Had to add it to digital_swig.i to properly wrap the parent functions into Python.
2011-08-10digital: updated constellation receiver to use loop bandwidth and damping ↵Tom Rondeau
factor instead of setting alpha and beta independently. Also cleaning up Costas loop a bit more.
2011-07-30digital: updated Costas loop again. The damping factor is now set by default ↵Tom Rondeau
and is no longer part of the constructor. All variables are exposed in gets and sets, though, for any purposes.
2011-07-30digital: better behavior of FLL code and added gets and sets for the ↵Tom Rondeau
frequency and phase estimates.

2011-07-19digital: moved gr_binary_slicer_fb to digital_binary_slicer_fb and added QA ↵Tom Rondeau
code. Removed constellation_decoder and everything that dependedon it. Must switch everything to digital_constellation_decoder now. Also moved gmsk to gr-digital. Make check passes.
2011-07-12fixing build for constellation code. Had to make some changes to the qa code ↵Tom Rondeau
to import the right stuff after being changed from sitting in gnuradio-core.

that it is in gr-digital.
2011-06-06digital: converting LMS algorithm to use the gr_adaptive_filter structure ↵Tom Rondeau
and making naming consistent (so CMA and LMS look and behave similary with different error and upate functions).
2011-06-06digital: formatting CMA code; adding get_ functions and renaming things for ↵Tom Rondeau
consistency.
