    Abstract: A communication device is operative to generate and orthogonal frequency division multiplexing (OFDM) symbol that includes one or more data and ranging modulation symbols. The data and ranging modulation symbols may be included within different sub-carriers of the OFDM symbol. The OFDM symbol is used to generate an OFDM symbol pair in the frequency domain (FDOM). After conversion from the FDOM to the time domain (TDOM), the OFDM symbol pair may then undergoes post-processing in the TDOM before transmission. Such post-processing may include the addition of cyclic prefix (CP) and cyclic suffix (CS) to the OFDM symbol pair in the TDOM as well as filtering using a window function. The OFDM symbol may be generated as an orthogonal frequency division multiple access (OFDMA) symbol, and two were more OFDM symbols or OFDMA symbols may be arranged in a frame.
