* Revert "Replace boost::any with std::any"Josh Morman2021-11-061-2/+2
| | | | This reverts commit ccd28dfbb1504fdc29db267acd8aa3354fe10cd2.
* Replace boost::any with std::anyMarcus Müller2021-10-281-2/+2
| | | | | | | | This is a modernization possible through C++17 Fixes #4780 Signed-off-by: Marcus Müller <mmueller@gnuradio.org>

* digital/chunks to symbols: be less inefficientMarcus Müller2021-07-271-2/+2
| | | | | | | | | | | | | The block formerly took the tags from get_tags_in_range (which are sorted), gave them to tag_checker, which sorted them, and then went through every input sample, checking its index against the next tag. Removed the tag_checker; that saves us a sorting of a sorted vector. The other optimization is to not dispatch any tag encountered to the own message handler; instead, the handler is called directly.

* digital: Add NRZI option to differential en/decoderDaniel Estévez2021-06-124-2/+37
| | | | | | | | | | | | | | | | | | | This adds an option to the differential encoder an decoder blocks to perform NRZI encoding and decoding. NRZI only makes sense with a modulus of 2, so the blocks constructors will throw and exception if passed nrzi = true and a modulus different from 2. The GRC blocks handle this by hiding the modulus field if the user selects NRZI encoding. A new unit test for the NRZI version of the blocks is added. Besides checking that encode plus decode gives the original, this test also compares the C++ implementation results against a Numpy implementation. Additionally, a faster implementation of differential encoding/ decoding for modulus 2 is included here. Signed-off-by: Daniel Estévez <daniel@destevez.net>
* digital: Remove crc32 utilityMartin Braun2021-05-222-44/+0
| | | | | | | | | | This patch removes a crc32 utility that used to be used in our CRC32 blocks, but no longer is. Right now, all this does is expose a generic CRC32 function to the user (both via Python and C++), but there are enough other libraries that let the user do that. Therefore, we'll remove this.

* digital: ofdm: Fix whitespace in OFDM chanest blockMartin Braun2020-12-191-25/+32

* digital: ofdm_equalizer_simpledfe: add enable_soft_output optionjapm482020-10-281-4/+14
| | | | | | | | | Enable outputting equalized symbols that are not exactly constellation symbols. This is useful for OFDM soft decoding/demodulation (e.g. optimal turbo or LDPC decoding). For compatibility, this new behaviour has to be enabled by setting the new option "enable_soft_output" to true (false by default).

| | | | | | | | | | | | | | | | | | * digital: restructure equalizers and add dfe This commit restructures the linear equalizer to have a separate specifiable adaptive algorithm. Generally this works the same as the previous LMS and CMA decision directed equalizers, but also adds the ability to equalize using training sequences as well. Also, a Decision Feedback Equalizer structure is added * digital: more const in equalizers * digital: equalizers - more safety based on review * digital: dfe - use deque instead of vector for decision_history * digital - equalizers, further cleanup

* digital: pfb clock sync: Remove deprecated set_taps() API callMartin Braun2020-01-062-24/+0
| | | | | | | This API call was deprecated a long time ago and contained a warning that it will be removed, so we're now being true to our promise. This also fixes a compiler error in SWIG *if* you have old headers installed that SWIG will find (instead of the ones in the source tree).
* Replace many `const` variables with `constexpr`Thomas Habets2020-01-041-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constexpr is like const but (for variables) guarantees evaluation at compile time (as opposed to runtime). Likely this change will do nothing on its own (though it could, since it gives the compiler more information). But it still has benefits. It allows programmer to know that initialization is not expensive (it was done at compile time), and reduces risk of a refactoring regressing the compiletimeness. Runtime initialization can be nonobvious in larger codebases. E.g.: struct S { static int foo(); }; const int bar = S::foo(); // Called and initialized at *runtime*. int S::foo() { return 10; } With constexpr: struct S { static constexpr int foo(); }; constexpr int bar = S::foo(); // Error: used before definition. constexpr int S::foo() { return 10; } Initializing at runtime is not just startup costs, but also can save memory since it'll end up in a R/O section of a binary and therefore doesn't need to be swapped out, but can be shared (in the mmap() sense of the word).
