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. ...

we dont use test() -> remove it Made the window for the pass band filters integers (take firdes.WIN_XXX). Evaluation fix in param.to_code(). Removed the flagging api and usage from the base classes. added ref scale param to fft and waterfall Switched the python classes to inherit from the base and gui classes. port and param types from an overloaded method todo Replaced TYPES in Port and Param with types parameter. made is_virtual_xxx a block level function, used by port and param classes added stream id type and checking in evaluate avoid loops Recursive resolution of virtual sources. added virtual source and added stream ids, logic to clone in port added rewrite methods to element to separate from validation logic Added virtual sink and logic to clone port. removed repurposing of pads Work on command line options for generated code. renamed the colors dialog to types use pkgpythondir ...

* Fixing a line in the clock recovery algorithm. This works with a bit larger error than there proably should be. * Adding clock sync algorithm using PFB. This works, but needs a bit more work.

2009-08-31Modified log power fft block so ref scale is peak to peak.Josh Blum
Tweaked fft sink autoscale routine to come up with better numbers. Modified scope sink ac couple block to use constant tap. The previous tap calculation would cause failure for very small sample rates.

Added files to Makefile.am for distribution. Added colorbar to spectrogram for magnitude measurement. Fixed spectrogram plotting axis. Adding a spectrogram plot. The axis need work. GR plotter tool handles end of file and files shorter than the block length. Manages window/filter types better. Disables filter types if the designing algorithm doesn't support it (no RRC or Gaussian for equiripple filters). User messages if PyQt and PyQwt are not installed (or found). Setting validators for all edit boxes. Fixing tab order. Adding display for the number of taps in the filter. Adding equiripple band reject filter to filter design app. Adding P-M version of band reject filter. Fixed documentation for optfir band pass filters. Added routine for optfir equiripple filter design code to create complex bandpass filters. Also adds this ability to the filter designer. Added design for Guassian filters. Added design for RRC filters. Added Band Notch filter Adding complex bandpass filter design (for windowed filters only). Adding plotting of group delay. Adding labels to the plots. ...
