ABSTRACT:
An interleaving apparatus and method for an OFDM transmitter are provided. The interleaving apparatus comprises a memory unit, a memory write/read control unit, a memory access address generation unit, and a second permutation and output selection unit. The memory unit includes a plurality of memory banks, which are capable of being independently controlled so that data can be written or read in/from the memory banks, each having memory cells arranged in an N×M matrix structure. The memory write/read control unit generates control signals to write/read data in/from the memory unit. The memory access address generation unit generates a memory access address used to write/read data in/from the memory unit in response to the memory write/read control signals. The second permutation and output selection unit rearranges the positions of data bits output from the memory unit and outputs the position-rearranged data bits.
