Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 13:48:01 2011 -0500

    Merge branch 'maint'

commit 59ae7f87cc52e28a39b04895f2977624552f6f1d
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 13:42:16 2011 -0500

    digital: somewhat strange buy necessary fix for autotools build with guile.

commit 6e52e9f86b40ccc38ee21068983936113e6b53dc
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 11:35:15 2011 -0500

    digital: added tag_nsamples placeholder into SNR probe block.
    
    The intent of this block is to be able to pass messages containing the SNR 
at a set number of samples.

commit 1091192d27aab20694e1597868df4962b39ad060
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 11:33:36 2011 -0500

    digital: adding SNR nsamples set/get functions in swig i file.

commit 8e134f11639deeadd0ed242e0f12360ef628d495
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 11:24:12 2011 -0500

    digital: fixed documentation of parameters.

commit ef4d48de26b64d89851a93fc5402b33fcc1a809f
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 11:10:23 2011 -0500

    digital: update to qa and example code for new constructor with 
tag_nsamples arg.

commit a4d62472975aaeb50fa96c360c4b24d3ad84cf6e
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 11:04:48 2011 -0500

    digital: the SNR estimator block now issues a tag with the SNR (key = 
'snr'). The number of samples between when the tag is sent is set in the 
constructor (default = 10000) and can be changed.

commit 0bf8934a7f1bf41916a5f7562b250c18a87034c7
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 10:58:58 2011 -0500

    digital: snr probe passing just the 0th input stream to SNR estimator.

commit 3d92c79e311f40cb2f3839b5ac68eab76c476408
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 30 10:58:04 2011 -0500

    digital: SNR estimators just take a complex vector; not full vector of 
complex vectors.

commit 36dda1f11620c6c9db63036d76a67b3be3f711bc
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 18:30:27 2011 -0500

    digital: added documentation for SNR estimators; made a Doxygen group for 
them. Also set the alpha value to a default of 0.001; most won't need to change 
this.

commit 062f4f37c8dd543cbd29ab4a4745534497c920a8
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 18:28:52 2011 -0500

    digital: fixed QA code for SNR estimator SVR name change.

commit 886e3c258ff40b4d10e7e8fc28912f14565a4fd1
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 15:38:49 2011 -0500

    digital: adding documentation for SNR estimators; added an estimator for 
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.

commit 2db40bb40eda996bf47417a04ec001acb422d3d9
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 12:38:27 2011 -0500

    digital: adding an example program for the SNR estimators with Python code 
to compare.

commit 91e29b5819955818671dae779203ffa8f49b66c4
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 12:37:14 2011 -0500

    digital: QA code for SNR estimators.

commit 55ff1160c9e0d49028c52296fa920428d30fd7c3
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 11:27:56 2011 -0500

    digital: fixing up blocks to use SNR est classes more appropriately.

commit 74c53aa4c5b9aeac590b803b12601bcc9c8b9b60
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 11:27:00 2011 -0500

    digital: added a probe (sink) for the new SNR estimators; also fixes up 
Makefiles and Swig files for SNR est blocks.

commit ceb18ce1c1342477d0704edfaa3e775830a999e4
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 10:54:52 2011 -0500

    digital: using impl SNR estimator classes instead of function pointers.

commit 858e3582a108cfea8040f59628698e9394558092
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 29 10:54:03 2011 -0500

    digital: made separate implementation classes for the different SNR 
estimators.

commit 6a78e0a8ae6dc17a12ab5e397f1452a1a363e7d1
Author: Tom Rondeau <address@hidden>
Date:   Fri Dec 23 13:28:06 2011 -0500

    digital: added a class, digital_mpsk_snr_est_cc, that estimates the SNR of 
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.

commit c1c68974a6677f6dd81b1fb6e3c129e8d08c1fd0
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 22 18:20:33 2011 -0500

    core: added accessors to get all settable values of the channel_model 
objects.

commit 5cd411a7e260b0721fecbac6c53b0717b2adf7e6
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 22 18:20:06 2011 -0500

    core: added accessors to noise_source to get type and amplitude of object.

commit 5faab4fbcf423cc614d53f0f3c557c2f055b7ed0
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 22 18:19:28 2011 -0500

    filters: added accessor functions to FFT and FIR filter classes to return 
vector of taps.

commit cb3289d1494339cb0ac20bed080a0d37b99ab4fb
Author: Tom Rondeau <address@hidden>
Date:   Thu Dec 22 18:00:47 2011 -0500

    digital: exposed setting FLL loop bandwidth factor in GRC; must have been 
overlooked initially.
