# fastfec
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 `3GPP` decoder, parallelized using the `SIMD` instructions.
## Usage
Add the crate to your `Cargo.toml` dependencies:
```toml
[dependencies]
fastfec = { git = "https://github.com/rmja/fastfec" }
```
