Abstract
To ensure a given quality of service in the networks of the Internet of Things, short error-correcting codes are used, in particular, low-density parity-check codes. The paper proposes an approach for decoding these codes based on the joint application of belief propagation and differential evolution procedures. It is shown that in order to reduce the search area of error vectors based on differential evolution, it is necessary to use the least reliable basis of the parity-check matrix. Flowchart and pseudocode of the combined decoding algorithm of short low-density parity-check codes were presented. The simulation results showed that the proposed decoding method provides an additional gain from encoding compared to the classical decoding method. The application of the presented iterative decoding method of short low-density parity-check codes will improve the efficiency of data transmission in the infrastructure of the Internet of Things.
