Abstract:
Systems and methods for signal analysis are described. The method can include digitizing a signal modulated by a pseudo noise (PN) sequence, dividing the digitized signal into a plurality of sample blocks, and estimating a PN phase embedded in a sample block of the plurality of sample blocks using an iterative message passing algorithm (iMPA) executed on a redundant graphical model.
