Method and system for calibrating a system parameter

Apparatus for performing signal correlation within a signal processing 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, cause the apparatus to perform operations comprising:

• receiving a plurality of signals from a plurality of remote sources;
• generating a plurality of local signals;
• correlating one or more of the local signals with a plurality of the received signals to generate a plurality of correlation results;
• compensating a phase of at least one of the local signals, the received signal, and the correlation results based on a plurality of hypotheses regarding at least one system parameter to generate a plurality of phase-compensated correlation results;
• combining the plurality of phase-compensated correlation results to generate a joint correlation score;
• determining a preferred hypothesis in the plurality of hypotheses that maximizes the joint correlation score;
• and
• using the preferred hypothesis to estimate a value of a parameter associated with the signal processing system.
