1. A transmitter producing an ultra-wide-band (UWB) physical layer using time-frequency interleaved (TFI) orthogonal frequency division multiplexing (OFDM) within the 3.1-10.6 GHz UWB band, the UWB physical layer comprising:

  • a band of frequencies divided into contiguous bands of tones;

    a plurality of OFDM symbols, each OFDM symbol having a plurality of tones from a respective contiguous band; and

    a data payload of the plurality of OFDM symbols for communication between the transmitter and a receiver, wherein consecutive OFDM symbols use different subsets of tones.
