    Abstract: An OFDM transmission apparatus having minimal transmission delay comprises a training symbol storage and generation unit, a delay unit and a controller. The training symbol storage and generation unit stores training symbols for the preamble, and outputs the stored training symbols when a training symbol output request signal is received. The delay unit receives data for the signal field from the MAC layer, delays the received data by the data processing time of the scrambler, and outputs the delayed data to the convolution encoder. The controller outputs the training symbol output request signal, requesting the preamble of the frame, to the training symbol storage and generation unit when a frame transmission request is received from the MAC layer, and outputs a data request signal, requesting the signal field and the data field, to the MAC layer in consideration of total data processing time (TPROCESS).

    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.
