fft_filter_fff now uses new class successfully and passes make check.

buggy in the transmitter due to the make packet padding to 512 bytes.

getting object names the same as DBPSK block.
|
|
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.

which makes the rest of the code work. My previous test cases must have masked the problem.

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

it for 0.5<=rate<=1.0 range.

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.
