High bandwidth data transport system

1. A method of data transmission, comprising the following steps:

(a) receiving at least one stream of data;

(b) framing the at least one 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 interleaved data symbol array;

(h) mapping FFT data output sub-channel to a frequency bin to provide frequency mapped data;

(i) performing an Inverse Fast Fourier Transform (IFFT) on the frequency mapped data;

(j) repeating steps (a)-(i) until an IFFT memory is full;

(k) serially transmitting the IFFT data as one-dimensional amplitude modulated ultra wideband impulses over a hard-wired medium;

(l) receiving the ultra wideband impulses over the hard-wired medium;

(m) recovering the IFFT data from the ultra wideband impulses;

(n) performing a FFT on the IFFT data;

(o) mapping frequency to sub-channel to provide mapped data;

(p) equalizing the mapped data by sub-channel;

(q) performing an IFFT to provide an IFFT output;

(r) mapping the IFFT output to data symbols;

(s) dc-interleaving the data symbols;

(t) decoding the symbols using a Reed Solomon decoder to provide the control data encoded bytes; and

(u) decoding the control data encoded bytes to create GFP bytes.
