* digital: switched digital components over to using LFSR class now in gr-analog.Tom Rondeau2012-10-301-1/+2
|
* digital: Add symbol output to constellation_receiver block for debugging.Ben Reynwar2012-10-151-4/+7
| | | | | | | | Cherry-picked from a commit on 'next.' Reworked for master style. Conflicts: gr-digital/lib/constellation_receiver_cb_impl.cc
* digital: Fixed scaling bug in QAM constellations.Ben Reynwar2012-09-301-0/+13
|
* digital: fix for FLL block; uses actual FIR filter.Hendrik van Wyk2012-07-081-29/+41
| | | | This should work much more efficiently and also appears to fix issue 463.

| | | | | | | | | | | | | | 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

* digital: copying over rest of blocks from gnuradio-core to gr-digital.Tom Rondeau2012-04-2320-4/+2417
| | | | | | Includes moving GRC and QA code; new ones where missing. Have not removed blocks from gnuradio-core for compatibility.

| * | digital: added tag_nsamples placeholder into SNR probe block.Tom Rondeau2011-12-301-5/+33
| | | | | | | | | | | | The intent of this block is to be able to pass messages containing the SNR at a set number of samples.
