Abstract

A method for generating a compound signal wave with one or more substantially sinusoidal waveform(s) containing an encoded digital information combined with a variable phase changing waveform(s) producing a compound notched sinusoid waveform including at least an amplitude-time modulated sine wave and at least one phase modulated wave(s). Presence or absence of change to a wave's sinusoidal amplitude within a phase indicates a data value. These data values can be changed within a data cycle or packet. Reduced modulation distortion is exhibited by amplitude-time modulation techniques when compared to classical amplitude modulation techniques. This reduced distortion in a communications signal results in increased effective transmission lengths, reduced error rates, higher data rates, and improved data security.

Description

[0001] Cross References to Related Applications [0002] This application claims Patent Application Serial No. 61 / 924,304, filed January 7, 2014, entitled "NuSine" and Patent Application Serial No. 14, filed December 18, 2014, entitled "Combined Amplitude-Time and Phase Modulation" / 574,577, both of which are incorporated herein by reference in their entirety. technical field [0003] The present invention relates generally to data transmission, and more particularly to sinusoidal modulation techniques that provide increased transmission rates. Background technique [0004] Transmission of digital data is typically accomplished from point to point by modifying one or more of the characteristic properties of the wave's amplitude, frequency, and phase to modulate a sine wave that is used as a carrier. [0005] Sine wave amplitude modulation has classically been achieved by directly varying the amplitude of a sine wave as a carrier wave in relation to the source to be transmit...
