The work on this crate is continued in https://github.com/rmja/fastfec

drone-fec

Blazing fast implmentation of various forward error correction algorithms optimized for embedded systems. The crate contains:

An 8-state BCJR 3GPP decoder, parallelized using the SIMD instructions for Cortex-M4.
A Turbo decoder.
An iterative QPP interleaver, with parameters from 3GPP.

Usage

Add the crate to your Cargo.toml dependencies:

[dependencies]
drone-fec = { git = "https://github.com/rmja/drone-fec" }
