* gr-fec: LDPC python function - making a better docstringtracierenea2016-04-051-5/+9
| | | | The help/docstring for this function was misleading and confusing even to myself!

* gr-fec: Adding doc in BER Curve Gen. block re: parallelism.tracierenea2016-03-271-0/+6
| | | | Adding documentation regarding parallelism configuration requirements for using the BER Curve Gen. block. Also adding a FIXME note so that we can better address this in the future. These notes are my understanding after getting clarification from Tom on how the parallelism feature behaves in this case.

* fec: LDPC: fixed issue with bit_flip_decoder.Tom Rondeau2015-10-151-10/+10
| | | | | We can't use a raw pointer, so using a shared_ptr to the base class, instead, from the H and G matrices.
* fec: LDPC: reworking code to make sure API is ok.Tom Rondeau2015-10-151-92/+100
| | | | | Reintroduced original ldpc_encoder for compatibility. Renamed new version to ldpc_par_mtrx_encoder.

|
* fec: LDPC: massive code clean up and change.Tom Rondeau2015-10-156-227/+286
| | | | | | | | | Squashed a number of commits to get to this point. Separated the H and G matrix concepts, make two different encoders and two different decoders. Removed gsl from API; now only an internal dep that we can replace more easily later. Working examples.

* fec: LDPC: Moving alist files to a more global place; updatingtracierenea2015-10-1515-18144/+1
| | | | | | | | | | | | example. Moved the LDPC alist files from the python and examples directories, installed them into $prefix/share/gnuradio/fec/ldpc. Updated CMakeLists.txt files accordingly. Consequently, updated the GRC LDPC example, which uses 2 of these files. I used the approach of gr-trellis where the path to the installed alist files is set by cmake.
* fec: LDPC: Adding capability to provide H matrix for encoding/decoding.tracierenea2015-10-151-2/+47
| | | | | | | | | | | | | - Adding new LDPC classes and example to doc - Editing the ldpc_gen_mtrx class to accept either a generator matrix (G) or a parity check matrix (H). - Renamed class from ldpc_gen_mtrx to ldpc_HorG_mtrx - Updated XML blocks and their documentation accordingly. - Deleting a matrix from examples dir that isn't use in any example. - Adding a simple matrix to example dir that is used in example.
* fec: LDPC: Workaround for swig issues, updating examples.tracierenea2015-10-152-0/+5925
| | | | | | | | | | | | | - separating LDPC BER curve stuff out from ber_curve_gen and making it a separate example (ber_curve_gen_ldpc.grc) - specifying that many functions are const - trying to be careful about the encoder/decoder classes not being able to modify the matrix objects - adding a get_base_ptr() function to the matrix child classes as a workout for swig and GRC. Issue described at: http://lists.gnu.org/archive/html/discuss-gnuradio/2015-02/msg00246.html
* fec: LDPC: Renaming class from ldpc_par_chk_mtrx to ldpc_R_U_mtrxtracierenea2015-10-151-14/+13
| | | | | | | | | To indicate that this matrix has a specific format, designed for use with the ldpc_R_U_encoder, renaming this class from ldpc_par_chk_mtrx to ldpc_R_U_mtrx. Also putting the memory free calls in the correct place in the bit flip decoder.
* fec: LDPC: Clean up, and adding LDPC to BER curve gen example.tracierenea2015-10-157-9356/+9403
| | | | | | | | | | | | | | | | | - The 6 alist files are just being re-pushed. git is saying they were modified on the remote but I didn't modify them, and couldn't solve that mystery. - CMakeLists.txt being updated to install the python script that generates matrices for use with LDPC encoder. Also it copies the alist files to python2.7/dist-packages/gnuradio/fec/LDPC - Adding the LDPC encoder/decoder to the ber_curve_gen.grc example. Note: the resulting plot shows LDPC performance as worse than the dummy encoder/decoder; so, still more work to do.... - Slight mod to the bit flip decoder to convert incoming floats to 0s and 1s, in the same manner as the repetition decoder.
* fec: LDPC: Adding scripts to generate matrices for encoder.tracierenea2015-10-152-0/+698
| | | | | | | | Adding python scripts which generate parity check matrices for use with the LDPC Richardson Urbanke encoder. A significant amount of matrix manipulation is required, so this process should be done before using the encoder at run time. For large matrices, it will take quite a while.
* fec: LDPC: Adding QA test and alist files.tracierenea2015-10-1514-0/+12439
| | | | | | | | | | Adding qa file - pretty much copied the structure of the dummy encoder/decoder qa file. Adding a small library of alist files, which are LDPC parity check matrix files that can be used with the Richardson Urbanke encoder. They have different rates and work with codeword lengths ranging between 100 and 1800 bits.
* fec: Adds MTU parameter to async and tagged stream blocks.Tom Rondeau2015-09-242-4/+5
| | | | | | | | | | The maximum transmission unit (MTU, in bytes) sets up the encoders and decoders with enough internal buffer space to accommodate frames of varying sizes up to the MTU. Proections placed to make sure incoming tagged streams and PDUs don't exceed this. This also fixes a bug in the tagged stream encoder and decoder blocks to properly use calculate_output_stream_length.
