Abstract:
A spread-spectrum signal receiving method in which a correlation operation is performed for obtaining a correlation between a base-band component of a received spread-spectrum signal and a spread code, so as to demodulate the received signal, said method comprising:a first correlation operation step for performing a correlation operation between the spread code and the base-band component;a second correlation operation step for performing a correlation operation at a timing equal to a timing difference between the spread code and the base-band component in said first correlation operation step, said timing difference being 1/2 of a spread-code interval; andan estimation step for estimating, based on results obtained in said first and second correlation operation steps, a correlation operation result at the timing point where a timing difference between the spread code and the base-band component is less than 1/2 of the spread-code interval.
