Abstract

A method of data transmission includes representing data using at least one amplitude modulated impulse based on an ultra wideband impulse, sending the at least one impulse over an electrically conductive guided media, receiving the at least one impulse over the electrically conductive guided media, recovering the data from the at least one amplitude modulated impulse after receiving the at least one impulse over the electrically conductive guided media. The at least one impulse coexists on the electrically conductive guided media with wave based transmissions sent over the electrically conductive guided media.

Claims

1. A method of data transmission, comprising:

creating a plurality of amplitude modulated impulses based on a ultra wideband impulse by;

(a) receiving at least one stream of binary data,

(b) framing the stream of data using Generic Frame Protocol (GFP) to provide GFP bytes,

(c) encoding the GFP bytes with control data to provide control data encoded bytes,

(d) encoding the control data encoded bytes with a Reed Solomon encoder to provide Reed Solomon encoded data,

(e) interleaving the Reed Solomon encoded data,

(f) determining bit loading per frequency bin based on channel estimation data to create a data symbol,

(g) performing a Fast Fourier Transform (FFT) on the data symbol to provide FFT data output,

(h) mapping the FFT data output to a frequency bin to provide frequency mapped data,

(i) peforming an Inverse Fast Fourier Transform (IFFT) on the frequency mapped data to provide IFFT data, and

serially transmitting the IFFT data as amplitude modulated ultra wideband impulses over an electrically conducting guided media during wave-based transmissions over the guided media.

2. The method of claim 1 wherein the guided media is a cable line.

3. The method of claim 1 wherein the guided media is a telephone line.

4. The method of claim 1 further comprising receiving the wideband impulses and extracting data associated with the plurality of impulses.
