G-LDPC DECODER AND G-LDPC DECODING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240106462 titled 'G-LDPC DECODER AND G-LDPC DECODING METHOD
Simplified Explanation
The G-LDPC decoder described in the patent application is a decoder that includes a Generalized Check Node Decoder and LDPC decoder circuitry. The Generalized Check Node Decoder groups connected variable nodes into groups in each iteration, generates test patterns based on messages received from the connected variable nodes, and identifies a value for a second message to be provided to the connected variable nodes. The LDPC decoder circuitry updates the value of variable nodes based on the second message received from the Generalized Check Node connected to each variable node.
- Generalized Check Node Decoder:
