Adaptive deactivation and zero-forcing scheme for low-complexity LDPC decoders

Abstract A modified message propagation algorithm is proposed for a low-complexity decoder of low-density parity-check (LDPC) codes, which controls the information propagated from variable and check nodes.The proposed threshold-based node deactivation for variable nodes and zero-forcing scheme for c...
