2010-05-23Merge remote branch 'gnuradio/wip/udp_source_sink'Johnathan Corgan
* gnuradio/wip/udp_source_sink: gnuradio-core: update copyrights gnuradio-core: allow swig to handle exceptions in UDP source/sink grc: update UDP source and sink block wrappers Simplify USE_SELECT usage Return immediately when using d_residual. Defend against a peer that sends an invalid message length. Move initialization of select timeout Correct update of d_temp_offset (parallel construction) Identify memory leaks that occur on error conditions Use -1 as file descriptor "not open" value instead of 0 Add additional conditionalization of networking includes Flush pending errors in gr_udp_sink on disconnect() Rework UDP source and sink, with incompatible API changes Updates to udp source/sink (select(), wait, cleanup) Discard data in gr_udp_sink until receiver is started. Use getaddrinfo in gr_udp_{source,sink} Changes to gr_udp_{source,sink} for MinGW Ignore ENOPROTOOPT return from setsockopt(SO_LINGER)
2010-05-21grc: update UDP source and sink block wrappersJohnathan Corgan
2010-05-18gnuradio-core: removed gr.dd_mpsk_sync_cc block as obsoleteJohnathan Corgan
2010-03-21Add new block gr.additive_scrambler_bb()Johnathan Corgan
This block performs scrambling by XORing the input sequence with the output of an LFSR. Repeating this operation restores the original sequence. (This differs from gr.scrambler_bb(), which convolves the input sequence with the LFSR output.) The additive scrambler allows an optional bit count after which the LFSR is reset to its initial seed. This allows use with, e.g., packetized fixed length payloads.

2009-12-03Allow for multiple io pads per hier flow graph.Josh Blum
Each io pad can have a different io signature. Uses the iosignaturev for hier implementation. Backwards compadible with exception: Pad blocks that used multiple ports must be replaced with multiple pad blocks as the new pad io blocks only support one port per block.

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.

2009-10-12Merge 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. ...

2009-10-03Added a run options to the "no gui" generate options.Josh Blum
The user can select between run to completion and prompt for exit. Also fixed the props dialog is changed function to have better hashes. Now we hash a tuple of all "relevant" items which is "order aware". Since xoring the individual hashes proved faulty when 2 params alternated hiding.
