Techniques for adaptive LDPC decoding

An apparatus for adaptive decoding, comprising:

• at least one processor configured to:
• receive a first set of values corresponding to a first low density parity check (LDPC) codeword and noise;
• perform a first plurality of iterations of an iterative decoding algorithm using a first set of decoding parameters to decode the received first set of values;
• compare a checksum value with a first threshold, wherein the checksum value corresponds to a number of parity check failures after the first plurality of iterations, and wherein the first threshold is defined based on at least one of:
• an error floor or a speed of the iterative decoding algorithm;
• and
• based on the compare:
• select a second set of decoding parameters for the iterative decoding algorithm;
• perform a second plurality of iterations of the iterative LDPC decoding algorithm using the second set of decoding parameters to decode the received first set of values and generate a first set of decoded bits;
• and
• a memory coupled to the at least one processor.

A non-transitory processor-readable medium for adaptive decoding, comprising processor-readable instructions configured to cause one or more processors to:

• receive a first set of values corresponding to a first low density parity check (LDPC) codeword and noise;
• perform a first plurality of iterations of an iterative decoding algorithm using a first set of decoding parameters to decode the received first set of values;
• compare a checksum value with a first threshold, wherein the checksum value corresponds to a number of parity check failures after the first plurality of iterations, and wherein the first threshold is defined based on at least one of:
• an error floor or a speed of the iterative decoding algorithm;
• and
• based on the compare:
• select a second set of decoding parameters for the iterative decoding algorithm;
• and
• perform a second plurality of iterations of the iterative LDPC decoding algorithm using the second set of decoding parameters to decode the received first set of values and generate a first set of decoded bits.
