Abstract

Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1GHz and lower frequency bands. In many embodiments the physical layer logic may implement orthogonal frequency division multiplexing symbols encoded with 32 sub carriers such as twenty data sub carriers four pilot sub carriers seven guard sub carriers and one direct current (DC) sub carrier. Many embodiments may transform the orthogonal frequency division multiplexing symbols between frequency and time domains with a 32 point fast Fourier transform or inverse fast Fourier transform. Some embodiments may up convert and transmit a communication signal with the orthogonal frequency division multiplexing symbols at one megahertz. Further embodiments may receive and detect communications signal with the orthogonal frequency division multiplexing symbols at one megahertz.
