Popis:	Abstract An area‐ and energy‐efficient encoding method and encoder architecture are proposed for the quasi‐cyclic low‐density parity check (LDPC) in near‐earth applications recommended by the Consultant Committee for Space Data Systems. The proposed encoding method reduces the computational complexity using a switch network before bit XOR operations in vector–matrix multiplication. A fully parallel LDPC encoder is implemented on the Taiwan Semiconductor Manufacturing Company 90 nm complementary metal oxide semiconductor (CMOS) technology, achieving a throughput of 10.06 Tbps with the lower area and energy utilization.
