US 10,382,246 B2 · Combined amplitude-time and phase modulation

Abstract

A system and method are provided relating generally to data transmission and more particularly to modulation techniques offering increased data transmission rates. To so provide, a first amplitude-time modulated (ATM) signal and a first phase modulated signal are combined at a first combiner to produce a complex wave modulation signal, and the complex wave modulation signal and an additional signal are combined at a second combiner to produce a second complex wave modulation signal. The additional signal may be a second ATM signal or a second phase modulated signal. Optionally, the second complex wave modulation signal and a second additional signal may be combined to produce a third complex wave modulation signal. In accordance with at least one embodiment, a shape of an element of information according to the first ATM signal may be defined programmatically over subportions of less than the duration of the element of information.
