Summary: | The embodiment of the invention discloses a data decoding method and device, equipment, a storage medium and a program product, and the method comprises the steps: obtaining original noisy data based on LDPC coding; determining a check matrix according to the original noisy data; according to the check matrix, performing one or more LDPC decoding operations on the original noisy data to obtain an iteration matrix; in each LDPC decoding operation, determining the number of unreliable variable nodes in a bipartite graph corresponding to the check matrix according to the numerical value of each element in the iteration matrix; and in response to the condition that the number of the unreliable variable nodes meets a preset early termination condition in the one or more LDPC decoding operations, stopping decoding.
