Not yet robust enough.
Inefficient QAM modulation/demodulation also added (via the generic implementation).

size_t (still unsigned). Fixes issue #304.
Also uses uint64_t's internally so everyone is always on the same type. This should not affect anyone's use of the block.

This reverts commit f23a2b33ca1bebf0c3a5fa26fdcff11827744b77.
This change introduced a segfault when calling into the gr_prefs module
during the gri_fft helper class constructor. Until this is debugged,
the functionality is being reverted.

Alexandru Csete:
The gr_agc2 block has public methods to set and get the AGC levels and
rates; however, only a few of these interfaces are exported to Python
and none of them are available in GRC.
The attached patch adds the missing public methods to gri_agc2_cc.i
and gri_agc2_ff.i and defines the corresponding callbacks in the
gr_agc2_xx.xml GRC block.

* patches/marcus/fftw:
gnuradio-core: allows configuring FFTW to use ESTIMATE vs. MEASURE
|
|
|
|
|
|
This change was needed because gr_ofdm_sampler derives directly from
gr_block, but functions (from the runtime's point of view) as a
decimator. It takes many items in to produce a single output
item. Without this change, values of fft_size > ~4096 would result
in the scheduler complaining that it could never fullfil the block's
request for samples.
When deriving from gr_sync_interpolator or gr_sync_decimator, their
constructors set the hint automatically.

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.

This merge adds polyphase clock recovery, implements new PAM demodulators
that use it, and also moves GRC examples to gnuradio-examples component.

* '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.

Adds several API functions to determine build constants at runtime, and
a convenience command line program to display them:
From C++:
const std::string gr_prefix();
const std::string gr_sysconfdir();
const std::string gr_prefsdir();
const std::string gr_build_date();
const std::string gr_svn_date();
const std::string gr_svn_version();
const std::string gr_version();
From Python:
gr.prefix()
gr.sysconfdir()
gr.prefsdir()
gr.build_date()
gr.svn_date()
gr.svn_version()
gr.version()
The new binary is 'gnuradio' and installed on the path:
$ gnuradio
Program options: gnuradio [options]:
-h [ --help ] print help message
--prefix print gnuradio installation prefix
--sysconfdir print gnuradio system configuration directory
--prefsdir print gnuradio preferences directory
--builddate print gnuradio build date (RFC2822 format)
-v [ --version ] print gnuradio version
--svnversion print SVN repository version (SVN format)
--svndate print SVN repository date

Adds --enable-python option to configure (defaults to yes).
Using --disable-python or --enable-python=no will cause only
C++ API targets to be created and installed.
Several new shared libraries are now created. Where in the past,
the C++ objects of the actual gnuradio blocks that were in a component
were hidden inside their corresponding Python extension modules, these
are now split out into a libgnuradio-foo.so library, and the _foo.so
Python module is linked to that. This has been the way several top-
level components have operated for some time, such as gr-audio-alsa
and gr-usrp and gr-usrp2. This changeset applies that pattern to all
components.
C++ API users can use pkg-config to discover the cflags and libs
parameters needed to include and link against these libraries.
These components have not been tested:
gr-comedi
gr-audio-osx
gr-audio-windows
Passes distcheck.
