TLDR
In this paper, the information signal in a satellite communications system is split into a first signal component and a second signal component, and then the first component is transmitted to a first system element and the second component is sent to a second system element.Abstract:Â
Methods of transmitting an information signal in a satellite communications system include splitting the information signal into a first signal component and a second signal component, transmitting the first signal component to a first system element of the satellite communications system, transmitting the second signal component to a second system element of the satellite communications system, combining the first signal component and the second signal component to form a combined signal, and recovering the information signal from the combined signal. Related systems and components are also disclosed.read more
