Abstract:
1. A method for transmitting data symbols in an orthogonal frequency division multiplexing (OFDM) system, the method comprising: identifying a number of data subcarriers of the OFDM system and a number of protection subcarriers of the OFDM system; generating two or more uncoded data symbols; generating one or more diversity coded data symbols by performing mathematical operations on the two or more uncoded data symbols in a Galois Field, the one or more diversity coded data symbols including a combination of the one or more uncoded data symbols and the diversity coded data symbols having the same number of bits as the two or more uncoded data symbols; transmitting, by a transmitter, each of the two or more uncoded data symbols on the number of data subcarriers of the OFDM system; and transmitting, by the transmitter, each of the one or more diversity coded data symbols on the number of protection subcarriers of the OFDM system.
