1. A method of receiving a signal comprising:
correlating a digital signal provided by a receiver with a motion compensated correlation code, wherein the motion compensated correlation code is a correlation code that has been compensated using one or more phasors, wherein the phasors represent a predicted evolution of a phase and/or amplitude of the digital signal over a specific period of time predicted using a motion of the receiver in a direction of a source of the digital signal over the specific period of time.
