1. A method comprising:
- processing a received satellite positioning system (SPS) signal to obtain a correlation peak detection in a code phase search window comprising a range of code phase hypotheses;
detecting two or more energy peaks in the processed SPS signal; and
altering the processing in response to detecting energy peaks spaced apart by more than a set spacing in the range of code phase hypotheses.

Abstract
The subject matter disclosed herein relates to a system and method for processing a signal received from a satellite positioning system (SPS) in the presence of a multi-tone jammer. In one particular implementation, processing of a signal may be altered in response to detection of one or more conditions.
