* | | | | | | Convert set_relative_rate(double) to the new integer or receiprocal callAndy Walls2018-08-235-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a mass conversion of existing set_relative_rate(double) calls to either the set_relative_rate(uint64_t, uint64_t) or set_inverse_relative_rate(double) calls, where ever easily possible and appropriate, to improve tag propagation precision for fixed relative rates.

* gr-fec: free memory for G matrix at end of constructortracierenea2016-04-062-8/+6
| | | | There's no reason to make the G matrix a data member of this class and keep it around in memory. It's not used for encoding or decoding, so once we've used G to get G' and H, we can free that memory.
* gr-fec: Fix memory allocation issue during encoding.tracierenea2016-03-282-39/+48
| | | | | | | | | | I think that declaring these temporary matrix variables in the header (and then allocating memory for them in the constructor) is problematic when using parallelism = 1 or 2, as is the case when using the BER Curve Gen./Sink blocks. When parallelism is in effect, there are multiple "sub" flowgraphs in process and therefore multiple, probably very-close-to-simultaneous, calls to encode(). I think what's happening is that these temp matrices are being overwritten in memory by the next call to encode() before the current call to encode() is done with them. I know that such repeated allocate/free calls in the encode() function is not ideal or efficient, I can't think of a better way to do this (for now) and allow for parallelism. With this change, these matrices are no longer member variables of the class, so I've removed the "d_" prefix from the variable names.

* fec: LDPC: patch for issue #847.Tom Rondeau2015-10-292-4/+9
| | | | | | | | GSL didn't introduce gsl_matrix_equal until 1.15 and GNU Radio only requires 1.10. This is an attempt to calculate if the two matrices are equal by subtracting one from the other and seeing if the max element is greater than 0 (all elements should be 0 if they are the same matrix).
* fec: LDPC: fixed issue with bit_flip_decoder.Tom Rondeau2015-10-157-26/+17
| | | | | 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 Rondeau2015-10-156-80/+229
| | | | | Reintroduced original ldpc_encoder for compatibility. Renamed new version to ldpc_par_mtrx_encoder.
* fec: LDPC: changing namespace of ldpc_encoder back.Tom Rondeau2015-10-152-96/+91
| | | | | Keep the original API for this class in 3.7. We should convert this to gr::fec::code in 3.8.
* fec: LDPC: massive code clean up and change.Tom Rondeau2015-10-1522-1423/+2095
| | | | | | | | | 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: Adding capability to provide H matrix for encoding/decoding.tracierenea2015-10-155-164/+266
| | | | | | | | | | | | | - 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: Updating decoder to handle parity bits either first ortracierenea2015-10-153-5/+24
| | | | | | | | | last. The convention (I hear) is that parity bits come last, at the end of the codeword. Richarson/Urbanke's encoding method has them first though. So, adding flexibility to handle either case; default is parity bits expected last.
* fec: LDPC: Workaround for swig issues, updating examples.tracierenea2015-10-159-24/+51
| | | | | | | | | | | | | - 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.
