2010-03-06Using better defaults for new FLL implementation.Tom Rondeau
2010-03-06Improved performance of FLL using a more robust error term.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.
2010-01-31Got this wrong before. Derivative filter taps are now calculated correctly ↵Tom
which makes the rest of the code work. My previous test cases must have masked the problem.
2010-01-17Adding FLL correction to DQPSK2 block.Tom
2010-01-02Printing FLL gain value in verbose mode.Tom
2010-01-02Since I'm bothering to average the error, I might as well use it.Tom
2009-12-20Adding FLL to DBPSK demodulator block. Need OTA testing.Tom
2009-12-20Adding some documentation.Tom
2009-12-20Cleaning up functions.Tom
2009-12-20WIP: better access to setting FLL parameters and working on getting gain ↵Tom
settings better.
2009-12-18New way to handle arbitrary resampler. Now featuring lower noise!Tom
2009-12-15Generating the band-edge filter taps based on the oversampling ratio ↵Tom
(samples per symbol), rolloff factor, and the prototype (matched) filter size.
2009-12-10Adding accessor functions to set alpha and beta gains for the FLL.Tom
2009-12-10Adding alpha and beta gains to FLL constructor.Tom
2009-12-09Adding a band-edge based frequency lock loop.Tom

2009-10-31core: added gr.pfb_clock_sync_fff based on _ccf version, updated exampleJohnathan Corgan
2009-10-29fixed issue where usrp siggen continued to transmit after program exitJosh Blum

2009-10-29Merge branch 'flattopwindow' of http://gnuradio.org/git/jblumJohnathan Corgan
Merge-fix: Remove debugging print Merge-fix: Update copyrights * 'flattopwindow' of http://gnuradio.org/git/jblum: Added window option to wxgui fft and waterfall sink. redid cos windows, added flattop and nuttall_cfd
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.

2009-10-21Merge branch 'vrt' of http://gnuradio.org/git/jblumJohnathan Corgan
Merge fix: added GRUEL_INCLUDES to vrt Makefile Merge fix: added missing include in gr-vrt * 'vrt' of http://gnuradio.org/git/jblum: query the model number from the host fix so all handlers get called on event simplfied the code while i was looking at it added access methods for gps stuff added access methods and parsing for caldiv if context use existing utility method reading the lo back and storing it use the new htonll and vrt types to send cal and lo freqs checking for if context packets and setting up the payload pointer and size Reading 64 bit freq out of chunk of context packet. copied over vrt context and type headers, updated bits.h as well Dump IF-Context packets in hex. use gruel/inet.h instead of arap/inet.h fix white space made rxdspno a parameter for: start/stop streaming, and quadradio32fc
2009-10-19Resampler seems to be working for all values of rateTom
2009-10-19Working on fixing arbitrary resampler not working for rate < 1.0; this fixes ↵Tom
it for 0.5<=rate<=1.0 range.
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. ...
