mfsk-core 0.4.0

Pure-Rust library for WSJT-family digital amateur-radio modes (FT8/FT4/FST4/WSPR/JT9/JT65/Q65): protocol traits, DSP, FEC codecs, message codecs, decoders and synthesisers — unified behind a zero-cost generic abstraction.

//! Generic DSP primitives shared by every MFSK protocol.
//!
//! Nothing in this module knows about FT8, FT4 or any specific modulation —
//! it operates on raw sample buffers, sample rates, and target frequencies.
//! Protocol-aware DSP (sync correlators, LLR, etc.) lives outside `dsp`.
