Abstract: 종래에는, 비정형환경하에서이동하는로봇, 예컨대실외에서실내로이동하는로봇이 GPS를수신할수 없는실내의음역지역으로이동하는상황에서는측위가어려워진다는문제가있다. 이에본 발명의실시예에서는, 비정형환경하에서이동하는로봇들간의통신을통하여애드-혹메시(ad-hoc mesh) 네트워크를구성하고, 로봇간의상대측위와로봇제어를통하여음영지역에서도위치측위가가능한시스템을구성하는실내외심리스(seamless) 무선위치측위기술을제안하고자한다.

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.
