Abstract
A receiver including a plurality of correlators to receive a satellite signal having a line of sight (LOS) component and a multipath (MP) component and generate correlator results corresponding to the received satellite signal. The receiver includes a peak search module to identify frequency peaks in the received satellite signal based on the correlator results, a peak selection module to identify the LOS component of the received satellite signal based on the identified frequency peaks and at least one of a code phase error module to generate a code phase error corresponding to the identified LOS component and a carrier frequency error module to generate a carrier frequency error corresponding to the identified LOS component. The plurality of correlators are further to generate the correlator results based on at least one of the code phase error and the carrier frequency error.
