Abstract

The invention discloses a low-energy-consumption LDPC encoder and method applied to an electric power Internet of Things system, and belongs to the field of wireless Internet of Things communication. The invention aims to solve the problem that the original communication system consumes more energy due to the fact that the coded information transmitted in the existing channel contains more high and low level transformations. The shift controller is used for sending a shift control signal to the shift register and the shift number storage module after receiving the coded signal; the shift register is used for converting a coded signal into a smooth signal and sending the smooth signal to the LDPC coded sequence composition module after receiving a shift control signal; the shift number storage module is used for receiving the coded signal and the shift control signal and calculating the digit of each high level in a smooth signal generated by the shift control signal in the coded signal, and the digit of the first digit of the coded signal is 0; and the LDPC coding sequence forming module is used for forming the smoothed signal and the digits into a serial signal and carrying out LDPC coding together to obtain an LDPC coding sequence. The method is used for reducing the number of changes of high and low levels in coded signals.

Description

technical field [0001] The present invention relates to LDPC encoders. It belongs to the field of wireless Internet of Things communication. Background technique [0002] With the rapid development of 5G, wireless IoT communication has gradually become possible from imagination. Through the communication system of the wireless Internet of Things, power companies can realize one-to-many wireless communication and remote control, which greatly saves manpower. The wireless Internet of Things system of the power system used at this stage usually produces too many high and low level changes during the coding process, resulting in relatively large energy consumption. [0003] The great transition of the signal throughput in the current equipment poses a relatively big challenge to each link in the encoding. Low-density parity-check codes (LDPC) were proposed by Gallager in his doctoral dissertation in the 1960s. This encoding method can well approximate the Shannon limit and h...
