2012-07-08digital: fix for FLL block; uses actual FIR filter.Hendrik van Wyk
This should work much more efficiently and also appears to fix issue 463.
2012-06-07fixed copyright dates.Tom Rondeau
2012-06-07Some really minor nits.Tom Rondeau
2012-06-06Block Modifications:Tim O'Shea
digital.mpsk_receiver_cc: Set reasonable default parameter values for GRC definition digital.ofdm_insert_preamble: Expose enter_preamble() as public, to allow external state changes Cleanup of incorrect forecast behavior Make the flag port optional, incase external preamble triggers are preferred to in-band gr_vector_source: added set_data( data ) and rewind() public methods gr_head: added set_length(int) method to modify head length New Blocks Added: gr_keep_m_in_n: Allows periodic extraction of M items instead of 1 (in keep_1_in_n) gr_pack_k_bits: Complementary block fo gr_unpack_k_bits gr_vector_insert_x: Complement to the gr_head block, inserts a vector into a stream then becomes a pass through
2012-04-24digital: moving generated chunks_to_symbols to gr-digital.Tom Rondeau
2012-04-23digital: copying over rest of blocks from gnuradio-core to gr-digital.Tom Rondeau
Includes moving GRC and QA code; new ones where missing. Have not removed blocks from gnuradio-core for compatibility.

2012-01-15digital: added get/set functions to mpsk_receiver_cc for theta (phase ↵Tom Rondeau
offset), omega relative limit, and modulation order.

2012-01-06Remove some more warnings. I'm probably being a bit OCD about these ones, ↵Tom Rondeau
but it makes the build output so much nicer...

2011-12-30digital: added tag_nsamples placeholder into SNR probe block.Tom Rondeau
The intent of this block is to be able to pass messages containing the SNR at a set number of samples.
2011-12-30digital: the SNR estimator block now issues a tag with the SNR (key = ↵Tom Rondeau
'snr'). The number of samples between when the tag is sent is set in the constructor (default = 10000) and can be changed.
2011-12-30digital: snr probe passing just the 0th input stream to SNR estimator.Tom Rondeau
2011-12-30digital: SNR estimators just take a complex vector; not full vector of ↵Tom Rondeau
complex vectors.
2011-12-29digital: adding documentation for SNR estimators; added an estimator for ↵Tom Rondeau
M2M4 type that allows the user to set the kurtosis of the signal and noise, if known, to work with non-MPSK and non-AWGN channels (untested). Also, the technique is signal to variation ratio (SVR), not SVN. Couldn't read my own writing.
2011-12-29digital: fixing up blocks to use SNR est classes more appropriately.Tom Rondeau
2011-12-29digital: added a probe (sink) for the new SNR estimators; also fixes up ↵Tom Rondeau
Makefiles and Swig files for SNR est blocks.
2011-12-29digital: using impl SNR estimator classes instead of function pointers.Tom Rondeau
2011-12-29digital: made separate implementation classes for the different SNR estimators.Tom Rondeau
2011-12-23digital: added a class, digital_mpsk_snr_est_cc, that estimates the SNR of ↵Tom Rondeau
an M-ary PSK signal. This block can calculate the SNR using 1 of 4 different methods specified in the block's constructor. They (tend to) trade off accuracy for computational performnace.

2011-09-01digital: adding CPM C++ hier block, which adds a hier directory to ↵Tom Rondeau
gr-digital. Reworked build system to include this in the libraries and modules built.
2011-08-30digital: fixing a few things left out in conversion to gri_control_loop ↵Tom Rondeau
children.
2011-08-30digital: converted mpsk_receiver to use gri_control_loop parent class. ↵Tom Rondeau
Updated QA code for this, too. Again, had to change the expected data since the loop converges at a different rate; tested by setting alpha and beta to old values and it worked with old data still.

2011-08-29digital: fixing qa code to test new dqpsk; a few minor formatting changes.Tom Rondeau
2011-08-29digital: created a separate DQPSK constellation that does not gray code ↵Tom Rondeau
inside the block. This forces a slower decision making routine but allows differential encoding. Gray coding is done using pre_diff_code.
2011-08-27digital: made digital constellation receiver a child of the second order ↵Tom Rondeau
control loop class and cleaned up the interface.

2011-08-14digital: cleaned up Costas loop code by switching over to the ↵Tom Rondeau
gri_control_loop class to handle the inner loop. Had to add it to digital_swig.i to properly wrap the parent functions into Python.
2011-08-10digital: updated constellation receiver to use loop bandwidth and damping ↵Tom Rondeau
factor instead of setting alpha and beta independently. Also cleaning up Costas loop a bit more.
2011-08-09digital: fixed complex M&M to output the error signal as a float. Also ↵Tom Rondeau
changed the error value limit since we were hitting it constantly before.
2011-07-30digital: update documentation.Tom Rondeau
2011-07-30digital: updated Costas loop again. The damping factor is now set by default ↵Tom Rondeau
and is no longer part of the constructor. All variables are exposed in gets and sets, though, for any purposes.
2011-07-30digital: better behavior of FLL code and added gets and sets for the ↵Tom Rondeau
frequency and phase estimates.
