Abstract: The present invention relates to an efficient method of calculating a coax network unit (CNU) for decoding a high-speed low density parity check (LDPC) based on a Digital Video Broadcasting-Satellite 2 (DVB-S2). According to the present invention, the efficient method of calculating the CNU for decoding the high-speed LDPC is configured to calculate the optimal CNU for high-speed decoding with a SC-NMS method to which a self-corrected method to an NMS (the efficient method of calculating the CNU for operating high-speed to obliterate a critical path and to reduce a clock cycle) assigning zero to a current edge through regarding no reliability if a code is changed by comparing values of the edge in the previous iteration with the value of the edge in the current iteration during decoding repetition.

Abstract: According to the present invention, the packet transmission time of a sensor node is reduced as the query is small and the length of a packet is closely related to the packet transmission time of the sensor node thus reducing energy consumption by performing a selective query to increase the time of a life than a conventional method. Additionally, the packet transmission time thereof is increased depending on the selective query and approximately 1.5% of energy is decreased in terms of energy consumption and the conventional method if the selective query is two, by which the simulation of the packet transmission depending on the selective query confirms the energy consumption of the sensor node and confirms a data success rate via the simulation when an event happens using an NS-2 simulator in order to compare of energy efficiency and the conventional method.
