2011-08-19Revert "gr-uhd: post received async messages to user supplied msg queue"Johnathan Corgan
This reverts commit 25b1550dba377b6dc86bee3e6f269a721efee655.
2011-08-19gr-uhd: add async metadata source blockThomas Tsou
Add asynchronous message "block" that is independent of normal gnuradio scheduler. The block instantiates a thread to wait for asynchronous messages from UHD and encapsulates them in a gr_message posted into a message queue. The interface is empty because the block is internally driven and accessed through the the constructor specified message queue.

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.
2011-08-14Convering the PLL refout block to use the gri_control_loop class to take ↵Tom Rondeau
care of the internal loop. The error and what to do with the phase and freq are left to this block. It also changes the interface so that the PLL's gains are determined by the loop bandwidth.
2011-08-14Adding a control_loop class that takes care of setting the loop gains and ↵Tom Rondeau
the standard loop advance function. This should be used as a parent class of any block that uses a 2nd order control loop (like the PLL, clock recovery, etc blocks).

2011-08-10Cleaning up; adding a different dbpsk that uses differential coding. The ↵Tom Rondeau
normal bpsk is non-differential by default, but can be set to use differential with the right flag.
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.
2011-08-09digital: fixing up receiver code. Almost there...Tom Rondeau
2011-08-09digital: setting up receive path to use new timing loop API, FLL API, new ↵Tom Rondeau
gain names/settings. Also added concept of gray coding to generic mod/demod and reworked bpsk/qpsk modulators so both work.
2011-08-09digital: fixed complex M&M to output the error signal as a float. Also ↵Tom Rondeau
changed the error value limit since we were hitting it constantly before.
2011-08-09digital: added M&M clock recovery loop as an option to compare against ↵Tom Rondeau

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.
