Abstract:
PROBLEM TO BE SOLVED: To provide an interleave/de-interleave device that can reduce the capacity of a memory. SOLUTION: In order to process a frame of source data for interleave/de- interleave or an interleaved data frame, the memory stores the frame in the interleave/de-interleave processing unit. While interleave/de-interleave is applied to the precedingly stored frame, since a symbol corresponding to the next frame is received and the memory storing it is required, the symbol is recorded to an address from which the symbol of the preceding frame is read without the need for the memory capacity to store the symbol of the succeeding frame.
