Abstract
A method for detecting a probe signal at an estimated code delay and an estimated doppler frequency includes: (i) dividing a period of the probe signal into sections each of a predetermined duration; (ii) assigning to each section one of a multiple code categories, each code category being indicative of a signal pattern of the probe signal within the section; and (iii) selecting multiple phase categories for a sinusoidal signal, each phase category being indicative of a range of phases in the sinusoidal signal. Thereafter, the method includes (i) receiving a signal from which the probe signal is to be detected; (ii) dividing the received signal into sections each of the predetermined duration; (iii) assigning each section of the received signal both a corresponding code category and a corresponding phase category, based respectively on the estimated code delay and the doppler frequency; and (iv) separately accumulating sections of the received signal according to the assigned code and phase categories of each section.
