Abstract
Apparatus and method for low density parity check code decoding in a first processing device, wherein the method includes receiving a first bit-word of a first length related to a log-likelihood ratio of a bit of a signal; obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word; and determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit-word.
Claims13
A method for use in low density parity check code decoding, wherein the method comprises:
- receiving a first bit-word of a first length related to a log-likelihood ratio of a bit of a signal;
- obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word;
- determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit-word.
An apparatus for low density parity check code decoding, wherein the apparatus comprises:
- a non-transitory computer readable medium storing instructions;
- at least one processor configured to execute the instructions to cause the apparatus to perform,
- receiving a first bit word of a first length related to a log-likelihood ratio of a bit of a signal;
- obtaining a second bit-word of a second length that is shorter than the first length, wherein obtaining the second bit-word comprises applying a correction to the first bit-word;
- determining a message depending on a set of second bit-words, wherein the set of second bit-words includes the second bit word.
