Patent ID: 8532206

Claim:
A method of creating a frame including an orthogonal frequency division multiplexing (OFDM) symbol generally used in a plurality of OFDM options, a maximum value among a repeated number of the same data by frequency domain spreading of the plurality of the OFDM options being N F , the method comprising: determining a number of coded bits to be processed per N F OFDM symbols based on N F and a size of an interleaver, the number of coded bits corresponding to N CBPS and the size of the interleaver corresponding to N cbps ; determining a number of data bits to be processed per OFDM symbol based on N CBPS and a coding rate, the number of data bits corresponding to N DBPS and the coding rate corresponding to R; determining a number of padding bits based on N DBPS , the number of padding bits corresponding to N PAD ; and generating, executed by a computer, a bit to be encoded by appending the N PAD padding bits to a physical layer header field.
