Method and apparatus for performing motion compensated signal processing

Apparatus for performing signal correlation within a positioning system, comprising at least one processor and at least one non-transient computer readable medium for storing instructions that, when executed by the at least one processor, causes the apparatus to perform operations comprising:

• determining a motion model of an antenna coupled to a radio receiver without using traditional inertial measurement unit (IMU) data;
• generating a plurality of phasor sequences, where each phasor sequence forms at least one hypothesis comprising a signal phase representing motion of the antenna;
• correlating at least one local signal with at least one received signal to produce at least one correlation result;
• compensating a phase of the at least one of the local signal, the at least one received signal or the at least one correlation result based on the at least one hypothesis regarding the determined motion model to generate a plurality of phase-compensated correlation results;
• determining a preferred hypothesis in the at least one hypothesis that optimizes the at least one correlation result of at least one of the phase-compensated correlation results;
• updating the motion model using a motion estimate associated with the preferred hypothesis;
• and
• improving radio receiver signal reception using the phase compensated correlation results.
