Method for evaluating binary offset coding reception signal of satellite navigation receiver, involves producing new particle of particulate filter around development point based on probability distribution density function

摘要

The method involves localizing a major peak of an autocorrelation function of a reception signal by using a particulate filter i.e. Kalman filter. A development point is selected from existing particles of the filter, where the development point is a particle with high probability for the major peak. A new particle of the filter is produced around the development point based on a probability distribution density function, which comprises high probability density in a range of distances of secondary maxima on right and left of the major peak.
