Abstract
Systems and methods are described for ultra-wide band high data-rate communications. A method includes A method of communications, includes: filtering a digital data pulse having a data clocking rate by mixing a filter-function pulse with the digital data pulse; generating a harmonic of a clock oscillator which appears as a center frequency of emission of frequency spread spectrum signal; and mixing the filtered digital data pulse with the harmonic of the clock oscillator signal, characterized in that the clock oscillator frequency, the data clocking rate, and the center frequency of signal emissions are harmonically related.

An apparatus, comprising:
- a digital filter implemented as the multiplication in a mixer of a filter-function pulse with a digital data pulse;
- a harmonic generator to generate a harmonic of a clock oscillator which appears as the center frequency of emission of a frequency spread spectrum signal;
- and
- a mixer for mixing the filtered data pulse and the harmonic signal,
- characterized in that the reference oscillator frequency, the data clocking rate, and the center frequency of signal emissions are harmonically related.
A method of transmitting, comprising:
- providing a reference signal having a frequency;
- providing an operating signal in response to a selection signal, wherein the operating signal has a frequency equal to the frequency of the reference signal multiplied by a number;
- and
- mixing the operating signal with a data signal to generate a transmission signal.
A method of receiving, comprising:
- providing an operating signal in response to a selection signal, wherein the operating signal has a frequency equal to a frequency of a reference signal, multiplied by a number;
- mixing the operating signal with a template signal to generate a first signal;
