generate an internal filter to cover the channel bandwidth; user can specify the attenuation of this filter if desired.

just specify the requested resampling rate without providing their own filter taps.
Taps are then generated inside hier_block2 to cover full bandwidth of input signal.
Optional attenuation parameter may be provided.

Ignores it if directory is now writable.

Also fixed gr_unittest.py to print to the screen and fail make check properly if there's an error.
Need to find a way to use XML runner with main() to fail make check and output to screen, too.

gr_unittest.py was updated to handle the path and file creation and run the XML runner
gr_xmlrunner.py is a public domain program written by Sebastian Rittau <srittau@jroger.in-berlin.de> (THANKS!) to extend Python's unittest module to handle XML JUnit format output. This was renamed from xmlrunner.py if any future work is done on it from our project as well as to keep the namespace clean and clear.
qa_skiphead.py is a first test program for the XML output. Creates an outputfile $HOME/.gnuradio/unittest/python/test_skiphead.xml.

* 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)

Remove source address specifications for sink; add connect() and
disconnect() to sink; add get_port() to source; add optional EOF
signaling (using zero-length packets) to sink and source; modify
dial_tone, vector, and audio examples to match new code; add qa
test case.

produces the correct output for oversampling_rate = 1.

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.

modulation_utils2 so only new modulator blocks work with the version 2 of everything. Also changed some internal names for clarity.

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.

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
|
|
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.

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

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.

set_enabled(bool) will either copy from input to output (True)
or drop the input on the floor (False).
