Decoding method for low-density parity-check code and system thereof
A decoding method for low-density parity-check (LDPC) code is provided and is configured to decode a communication protocol, which is pending to be tested. The communication protocol includes a code word, and the code word includes a code rate. The decoding method includes: receiving the code word of the communication protocol, which is pending to be tested; determining a parity-check matrix according to the code rate of the code word and saving the parity-check matrix in a dynamic memory; moving the parity-check matrix from the dynamic memory to a first memory and saving the code word in a second memory; sequentially transmitting the code word from the second memory to a plurality of check node units to calculate according to the parity-check matrix in the first memory; transmitting the code word verified by the check node units back to the second memory.
