Abstract

Abstract:
This paper study the behavior of multiple signal classification (MUSIC) algorithm for
suppressing correlated and uncorrelated jammers to GPS receiver. Simulation indicates
that MUSIC can cancel dramatically high power jammers for both types of signals and
perfectly detects their direction of arrivals. It also can suppress both jammers of
decreased powers up to -120 dBW. At that power level the suppression behavior
regarding to uncorrelated jammer is better than that for correlated one but the algorithm
still detects the correlated and uncorrelated jammers direction of arrivals.
