PURPOSE: A symbol-bit wise interleaving and de-interleaving method is provided to perform an interleaving and a de-interleaving by a two-dimension unit of a symbol and a bit. CONSTITUTION: In a symbol-bit wise interleaving and de-interleaving method, a transfer packet, which consists of plural symbols(S0-S11) of predetermined bits(b0-b4), is sequentially written to a symbol-bit interleaving map in the order(S0,S1,S2,S3,S4,S5,S6,S7,S8,S9,S10,S11). After writing the transfer packet to the symbol-bit interleaving map, a read operation is performed in a two-dimension row direction(S0b0-S11b0,S0b0-S11b1,S0b2-S11b2,S0b3-S11b3) of a symbol and a bit of the symbol-bit interleaving map.
