Abstract
A method for determining bit boundary of a navigation bit of a satellite signal received by a receiver is disclosed. The method includes dividing an assumed navigation bit equally into a plurality of power units, calculating unit powers of each of the plurality of power units, and determining a plurality of phases. Each of the plurality of phases is associated with an estimated bit boundary. The method further includes adding unit powers of the plurality of power units to obtain a plurality of bit powers. Each of the plurality of bit powers corresponds to the estimated bit boundary associated with one of the plurality of phases. The bit boundary of the navigation bit is determined based on the plurality of bit powers.
