Abstract
A transmitted reference ultra-wide band communication signal embodied in an electromagnetic wave and configured to communicate a data value includes a first frame having a first reference pulse and a first data pulse. The first reference pulse has a reference polarity and the first data pulse has a data polarity. The first reference pulse is separated from the first reference pulse by a delay time. The reference polarity is set based on a predetermined reference value and a first pseudo-random polarity code sequence, and the data polarity is set based on the data value and a second pseudo-random polarity code sequence. A receiver configured to receive the signal, a transmitter configured to transmit the signal, and a system of transmitters and receivers are also provided.
