Abstract
The present disclosure describes techniques for pre-scaling decoder input values. In some aspects a soft-decoding input indicating a reliability of an encoded bit is received, the soft-decoding input is scaled based on a value of the soft-decoding input, and a hardware-based soft-decoder is enabled to use the scaled soft-decoding input to decode the encoded bit. By so doing, resolution of the soft-decoding input can be preserved during subsequent decoding operations improving performance of the hardware-based soft-decoder.
