2010-03-14Fixing copyright dates.Tom Rondeau
2010-03-14Making old and new digital modulations completely seperable by adding ↵Tom Rondeau
modulation_utils2 so only new modulator blocks work with the version 2 of everything. Also changed some internal names for clarity.

2010-03-13Adding version 2 of receive path so as not to affect old dbpsk and dqpsk ↵Tom Rondeau
operations.
2010-03-06Using better defaults for new FLL implementation.Tom Rondeau
2010-02-27Fixing logging in new DBPSK and DQPSK.Tom Rondeau
2010-02-26Fixing a few bugs in handling of real samples per symbol.Tom Rondeau
2010-02-09Removing resampler from usrp transmit path as its taken care of in the ↵Tom Rondeau
modulators.
2010-02-08Setting up code to handle setting of samples per symbol properly. Still ↵Tom Rondeau
buggy in the transmitter due to the make packet padding to 512 bytes.
2010-02-01Fixing DQPSK block to work with any real value samples per symbol and ↵Tom
getting object names the same as DBPSK block.
2010-01-31Using PFB resampler to do the RRC filtering on the modulator. This along ↵Tom
with the PFB clock recovery in the demod block allows arbitrary real numbers for the number of samples per symbol. We will have to chance the transmit and recieve path code in the examples to take advantage of this.

2009-10-28Added window option to wxgui fft and waterfall sink.Josh Blum
Added rectangular window function to window.py. Average stays hidden in waterfall, fft, and numbersink wrappers (only avg_alpha shows/hides). Fixed options in waterfall wrapper to model after fft and numbersink average params.

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 ...
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.

2009-08-25Merge utils from http://gnuradio.org/git/trondeau.gitJohnathan Corgan
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. ...
