System and method for ultra wideband communications using multiple code words

A method for operating a wireless transmitter, comprising:

• transmitting a first plurality of wavelets arranged according to a first analog code word format, for use in a first operation at a wireless receiver;
• and
• transmitting a second plurality of wavelets arranged according to a second analog code word format, after transmitting the first plurality of wavelets, for use in a second operation at the wireless receiver,
• wherein the first analog code word format is different from the second analog code word format.

A wireless device, comprising:

• a plurality of stored code word registers for providing a plurality of first multiplexer input signals;
• a first multiplexer for choosing one of the plurality of first multiplexer input signals to pass as a first multiplexer output signal;
• a plurality of operational code word registers for selectively receiving the first multiplexer output signal from the first multiplexer, and for providing a plurality of second multiplexer input signals;
• and
• a second multiplexer for choosing one of the plurality of second multiplexer input signals to pass as a second multiplexer output signal,
• wherein each of the plurality of operational code word registers stores a code word for use in a different operation in the wireless receiver.
