LDPC decoding with on the fly error recovery

摘要

It is decided whether to adjust data associated with a decoder. In the event it is decided to adjust the data associated with the decoder, the data is adjusted to obtain adjusted data and decoding is performed on the adjusted data. In the event it is decided to not adjust the data associated with the decoder, decoding is performed on the data associated with the decoder.

1. A method, comprising:
deciding whether to adjust a finite impulse response (FIR) signal using a schedule that includes: (1) a number of unsuccessful iterations performed during soft output Viterbi decoding and (2) a number of unsuccessful iterations performed during low-density parity-check (LDPC) decoding; deciding whether to adjust a soft output from a soft output Viterbi decoder using the schedule; in the event it is decided to adjust the FIR signal:
adjusting the FIR signal to obtain an adjusted FIR signal; andusing the soft output Viterbi decoder to perform Viterbi decoding on the adjusted FIR signal; in the event it is decided to not adjust the FIR signal, using the soft output Viterbi decoder to perform Viterbi decoding on the FIR signal; in the event it is decided to adjust the soft output:
adjusting the soft output to obtain an adjusted soft output; andusing an LDPC decoder to perform LDPC decoding on the adjusted soft output; and in the event it is decided to not adjust the soft output, using the LDPC decoder to perform LDPC decoding on the soft output.
