A method is proposed for utilizing a memory of a de-interleaving unit comprising the steps of determining a size of the memory according to a maximal symbol number of a data frame, a delay value, an adjustable parameter, and a half of a total symbol number of the data frame; accessing the memory according to a write memory address determined by a first algorithm during data buffering; and accessing the memory according to a read memory address determined by a second algorithm during data retrieving. The conventional access method has the drawback of ineffective use of the memory space of the de-interleaving unit, while the proposed method uses only about half the memory space for implementation.
