Abstract
Preparing data for transmission includes determining bit loading per frequency bin based on channel estimation data to create a data symbol, performing a Fast Fourier Transform (FFT) on the interleaved data symbol array, mapping FFT data output sub-channel to a frequency bin to provide frequency mapped data, and 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. To recover the data a reverse process is used.
