摘要：

This paper proposes a pattern based Low-density parity-check (LDPC) codes scheme to reduce the decoding complexity using logical XOR. New approaches to this paper describe the pattern based encoder which using logical XOR operation. The proposed scheme can reduce iteration, complexity and packet errors while decoding procedures. It can obtain enhanced throughput performance and at receiver sides in several Signal to Noise Ratio (SNR) levels. Simulation results show that the proposed method can improve the throughput and transmission delay for wireless sensor networks.
