Patent ID: 8451879

Claim:
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.
