Fast implmentation of various forward error correction algorithms optimized for embedded systems. The crate contains:
- A Convolutional encoder and BCJR decoder.
- A Turbo encoder and decoder.
- An iterative QPP interleaver, with parameters from
3GPP. - Rate matching puncturer.
- An 8-state BCJR
3GPPdecoder, parallelized using theSIMDinstructions.
Add the crate to your Cargo.toml dependencies:
