2009-10-12Merge branch 'sync' of git@gnuradio.org:trondeau into masterJohnathan Corgan
This merge adds polyphase clock recovery, implements new PAM demodulators that use it, and also moves GRC examples to gnuradio-examples component. See merge commit diff for updated files post merge. * 'sync' of git@gnuradio.org:trondeau: (54 commits) Reverting dqpsk to be mpsk_receiver based and not change its behavior. Fixing initialization of timing gains. Alpha should be < 1, and beta should be << 1. 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. Fixing compiler warnings. Adding dqpsk2 block to makefile for installation. Adding DQPSK version that uses the PFB timing sync block (dqpsk2). Minor fixes for logging. Fixing import of UI file. Temporary working dbpsk2 example until we match everything. Working DBPSK implementation with new PFB clock recovery block. The feedforward AGC wasn't playing nicely, the frequency aquistion range was increased to swing half the sample rate in either direction, and the number of filter phases to use was increased to 32. A bit of code cleanup. Starting to rework QT app to control new PFB clock recovery alg. Making old dbpsk work again to compare against new version. Adding new DBPSK block with new PFB clock recovery alg. Revert "More additions to PAM timing simulation." More additions to PAM timing simulation. Using 2-PAM by default. Cleaning up GRC PAM timing example and adding ability to do M-ary PAM. Cleaning up constructor. Moving filter number decision to start work function. ...

set_enabled(bool) will either copy from input to output (True) or drop the input on the floor (False).

Adds several API functions to determine build constants at runtime, and a convenience command line program to display them: From C++: const std::string gr_prefix(); const std::string gr_sysconfdir(); const std::string gr_prefsdir(); const std::string gr_build_date(); const std::string gr_svn_date(); const std::string gr_svn_version(); const std::string gr_version(); From Python: gr.prefix() gr.sysconfdir() gr.prefsdir() gr.build_date() gr.svn_date() gr.svn_version() gr.version() The new binary is 'gnuradio' and installed on the path: $ gnuradio Program options: gnuradio [options]: -h [ --help ] print help message --prefix print gnuradio installation prefix --sysconfdir print gnuradio system configuration directory --prefsdir print gnuradio preferences directory --builddate print gnuradio build date (RFC2822 format) -v [ --version ] print gnuradio version --svnversion print SVN repository version (SVN format) --svndate print SVN repository date $ git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11418 221aa14e-8319-0410-a670-987f0aec2ac5

2009-05-27Merged r11123:11148 from jcorgan/np into trunk.jcorgan
Adds --enable-python option to configure (defaults to yes). Using --disable-python or --enable-python=no will cause only C++ API targets to be created and installed. Several new shared libraries are now created. Where in the past, the C++ objects of the actual gnuradio blocks that were in a component were hidden inside their corresponding Python extension modules, these are now split out into a libgnuradio-foo.so library, and the _foo.so Python module is linked to that. This has been the way several top- level components have operated for some time, such as gr-audio-alsa and gr-usrp and gr-usrp2. This changeset applies that pattern to all components. C++ API users can use pkg-config to discover the cflags and libs parameters needed to include and link against these libraries. These components have not been tested: gr-comedi gr-audio-osx gr-audio-windows Passes distcheck. git-svn-id: http://gnuradio.org/svn/gnuradio/trunk@11150 221aa14e-8319-0410-a670-987f0aec2ac5
