Abstract
An approach is provided for decoding a low density parity check (LDPC) coded signal. Edge values associated with a structured parity check matrix used to generate the LDPC coded signal are retrieved from memory. The edge values specify the relationship of bit nodes and check nodes, and are stored within memory according to a predetermined scheme that permits concurrent retrieval of a set of the edge values. A decoded signal corresponding to the LDPC coded signal is output based on the retrieved edge values.
Claims6
A method comprising:
- receiving a radio communications signal;
- and
- decoding the received radio communications signal according to a low density parity check (LDPC) code, wherein the LDPC code has a parity check matrix with a structure that enables concurrent retrieval of edge values for a set of M bit nodes or a set of M check nodes associated with the LDPC code in a partially parallel decoding process.
An apparatus comprising:
- a receiver circuit configured to receive a radio communications signal;
- and
- a decoder circuit configured to decode the received radio communications signal according to a low density parity check (LDPC) code, wherein the LDPC code has a parity check matrix with a structure that enables concurrent retrieval of edge values for a set of M bit nodes or a set of M check nodes associated with the LDPC code in a partially parallel decoding process.
