Abstract
This paper provides a direct and fast acquisition algorithm of civilian long length(CL) codes in the L2 civil(L2C) signal. The proposed algorithm simultaneously reduces the number of fast Fourier transformation(FFT) correlation through hyper code technique and the amount of points in every FFT correlation by using an averaging correlation method. To validate the proposed acquisition performance, the paper applies this algorithm to the real L2C signal collected by the global positioning system(GPS) L2C intermediate frequency(IF) signal sampler—SIS100L2C. The acquisition results show that the proposed modified algorithm can acquire the code phase accurately with less calculation and its acquisition performance is better than the single hyper code method.
