ABSTRACT:
An ultra-wideband transmitter is provided. In one embodiment, the transmitter uses a monopulse of a continuous cyclic signal to phase shift a data pulse. The data pulses and the cyclic signal may be modulated by varying a phase of the data pulses and cyclic signal. The phase shifted data pulse may be used to generate an ultra-wideband pulse for transmission. The modulated data pulses and cyclic signal may be gated such that the data pulse and only a monopulse of the cyclic signal pass through the logic gate. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.
