Complexity and energy-efficiency are viewed as two main factors of design error correct coding for the wireless sensor networks. First of all, this paper presents a Weighted Hard-Input Hard-Output (WHIHO) iterative decoding algorithm with the low complexity when the required bit error rate (BER) is satisfied for wireless sensor nodes. A reliability matrix from four different aspects of the decoding process, properly weighs and combines their respective reliability measures, and then employs the combined measure to make a judgment with regard to whether each received bit is correct or not. Next, the energy efficiencies of turbo product codes using HIHO and WHIHO decoding algorithm are analyzed. Simulation results in a BER curve indicating that the WHIHO decoding algorithm can achieve a better tradeoff between reliability and complexity, which compared with conventional HIHO and soft-input and soft-output (SISO) decoding algorithms. The simplicity and effectiveness of WHIHO decoding algorithm makes it a promising candidate for the application for wireless sensor network.
