Abstract:
A communication device includes a communication interface and a processor. In one example, the processor generates an orthogonal frequency division multiplexing (OFDM) symbol that includes information modulated within sub-carriers and then interleaves the sub-carriers of the OFDM symbol to generate an interleaved OFDM symbol. This interleaving of the sub-carriers operates to write the plurality of sub-carriers to rows of a two dimensional (2D) array and read the plurality of sub-carriers from columns of the 2D array. This interleaving also operates to read a column of the columns using a bit-reversed address of the column when the bit-reversed address is less than a number of the columns and using the address of the column when the bit-reversed address is greater than or equal to the number of the columns. The processor transmits, via the communication interface, the interleaved OFDM symbol to another communication device.
