a transmitter node and a receiver node, wherein each node of the transmitter node and the receiver node comprises:
a communications interface comprising at least one antenna element; and
a controller operatively coupled to the communications interface, the controller including one or more processors, wherein the controller has information of own node velocity and own node orientation;
wherein each node of the transmitter node and the receiver node are time synchronized to apply Doppler corrections associated with said node's own motions relative to a stationary common inertial reference frame;
wherein the stationary common inertial reference frame is known to the transmitter node and the receiver node prior to the transmitter node transmitting a plurality of signals to the receiver node and prior to the receiver node receiving the plurality of signals from the transmitter node;
wherein the receiver node is configured to digitize the plurality of signals using a step size, determine a modulation amplitude of the plurality of signals, and adjust the step size based on the modulation amplitude.
