2013-01-18digital: Updated constellation_receiver_cv documentation.Ben Reynwar
2012-10-30digital: switched digital components over to using LFSR class now in gr-analog.Tom Rondeau
2012-09-30digital: Fixed scaling bug in QAM constellations.Ben Reynwar
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.
2012-06-06Block 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

2012-05-20docs: fixing up docs from sphinx warnings.Tom Rondeau
2012-05-15digital: these classes are part of the digital libraryJosh Blum
2012-04-24digital: moving generated chunks_to_symbols to gr-digital.Tom Rondeau
2012-04-23docs: adding documentation for new gr-digital blocks.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.

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: fixed documentation of parameters.Tom Rondeau
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 estimators just take a complex vector; not full vector of ↵Tom Rondeau
complex vectors.
2011-12-29digital: added documentation for SNR estimators; made a Doxygen group for ↵Tom Rondeau
them. Also set the alpha value to a default of 0.001; most won't need to change this.
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.
