1. A device for ultra wideband communications over a guided medium, comprising:
- a line interface configured for electrical communication to the guided medium and adapted for interfacing with the guided medium;
an ultra wideband impulse transmitter electrically connected to the line interface for transmitting amplitude modulated ultra wideband impulses over the guided medium; and
an ultra wideband receiver electrically connected to the line interface for receiving amplitude modulated ultra wideband impulses over the guided medium;
wherein the device is adapted for preparing data for transmission using the ultra wideband impulse transmitter by;
(a) determining bit loading per frequency bin based on channel estimation data to create data symbols;
(b) performing a Fast Fourier Transform (FFT) on an array of the data symbols;
(c) mapping FFT data output sub-channel to a frequency bin to provide frequency mapped data;
(d) performing an Inverse Fast Fourier Transform (IFFT) on the frequency mapped data to provide IFFT frequency mapped data suitable for transmission using one-dimensional amplitude modulated ultra wideband impulses representing the IFFT frequency mapped data; and
wherein the device is adapted for (a) recovering data from the amplitude modulated ultra wideband impulses received by the ultra wideband receiver;
(b) performing a FFT on the data;
(c) mapping frequency to sub-channel to provide mapped data;
(d) equalizing the mapped data by sub-channel to provide equalized mapped data;
(e) performing an IFFT on the equalized mapped data to provide an IFFT output; and
(f) mapping the IFFT output to data symbols to thereby provide for recovering information communicated over the guided medium to the ultra wideband receiver.
