Abstract

See full text

Embodiments may comprise an orthogonal frequency division multiplexing (OFDM) system operating in the 1 GHz 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.
