Struct Aminstari8JonesPartialHardLimit

pub struct Aminstari8JonesPartialHardLimit { /* private fields */ }

LDPC decoder arithmetic with 8-bit quantization and the A-Min*-BP described in [3].

This is a DecoderArithmetic that uses i8 to represent the LLRs and messages and computes the check node messages using an approximation to the min* rule.
