Abstract

A novel communications method for generating specific unique information containing waveforms, for geometrically modulating a signal with those waveforms, and an apparatus for generating the waveforms, geometrically modulating carrier waves with those waveforms, or broadcasting the novel waves by RF, microwave, electric cable, or fiberoptic conduits.

wherein θ

is the angle in radians of the waveform;

T is an integer from 1 to ∞

representing the truncation point of the formula; and

R(θ

) represents an amplitude of the waveform, the system comprising;

an oscillator that receives an input and generates a binary coded decimal output;

a binary counter that receives the binary coded decimal output and generates a binary signal;

an EPROM that receives the binary signal at an address and generates an output corresponding to a number contained at the address;

a digital-to-analog converter that converts the number into a voltage value; and

a signaling power supply that receives the voltage value and generates the waveform.

2. A system as claimed in claim 1, wherein the waveform is modified to contain additional data.

3. A system as claimed in claim 1, wherein the waveform comprises electromagnetic radiation.

4. A system as claimed in claim 3, wherein the electromagnetic radiation is one of electricity or light.

5. A system as claimed in claim 3, wherein the electromagnetic radiation is one of radio frequency-transmitted radiation or microwave-transmitted radiation.
