Abstract
Forward error correction (FEC) decoders, such as Low Density Parity Check (LDPC) decoders are described. Described FEC decoders minimize the number of internal bits in a layered processor of an LDPC decoder while maintaining high coding gain operation of the LDPC decoder. Minimizing the number of internal bits in a layered processor is achieved by non-linearly companding the soft information into lower precision format while maintaining the dynamic range of the data bits. Described FEC decoders may generate updated soft information having a precision that is equal to the channel precision.
