A theoretical combination of frequency modulation and Doppler Effect

Abstract

This paper presents a theoretical combination of frequency modulation and Doppler Effect. We consider a single frequency source which moves on a path depending on a message and we will show in the simulation results that a receiver which is sufficiently far away from the source receives the FM wave corresponding to the message. We discuss on two of the most important possible paths in detail. These two paths are linear path when the message controls the source's velocity and circular path when the message controls the angel of movement. Also we show the simulation results of these two states and from these results, the modulated message in both states is the same as the modulated message in other common ways, however modulation in this way is directive and could be done in low power and these could be considered as some advantages of this method.
