Abstract: PURPOSE: A residual frequency estimator is provided to minimize loss caused in an AGPS(Assisted Global Positioning System) receiver during synchronous integration and asynchronous integration and more reliably detect signals in a region with low intensity of GPS signals. CONSTITUTION: A plurality of correlators(104) divides data bit stream of a received signal by a predetermined cycle and outputs the divided signals. An FFT unit(108) receives data bit streams of regular length output from the correlators and implements FFT(Fast Fourier Transform). An asynchronous accumulator(110) asynchronously accumulates the FFT-processed bit streams. A coarse residual frequency estimator(114) searches the maximum value exceeding a predetermined threshold from the frequencies of the asynchronously accumulated signals and calculates an estimated residual frequency. A fine residual frequency estimator(116) computes the estimated residual frequency through MLE(Maximum Likelihood Estimation) to obtain the final estimated residual frequency.
