Closed Form Delay/Doppler/Propagation Factor Acquisition for GPS Signals
Authors: , ,
Abstract: In this article, a delay/Doppler/propagation factor acquisition method for global positioning system (GPS) signal is proposed. Utilising the Fourier transform (FFT) of the autocorrelation function (ACF) for the received signal, together with some mathematical simplifications, a closed form solution is derived to estimate the delay/Doppler/propagation factor for the received signal. Unlike previous related estimation methods for this case, the proposed method has the advantage of not requiring any searching over the different parameters to perform the estimation. Simulation results for the proposed method are presented in this article to assess its performance.
