1. A method comprising:

  • generating a stream of frames from blocks of information bearing symbols by applying an orthogonal set of spreading codes to the block of information bearing symbols to form frames and interleaving the frames corresponding to different block of information bearing symbols to form the stream of frames;

    generating a stream of chips from the stream of frames by applying an orthogonal set of time-hopping spreading codes to the stream of frames to form chips and interleaving the chips corresponding to different frames to form the stream of chips; and

    outputting an ultra wideband (UWB) transmission signal from the stream of chips.
