Abstract

A signal-acquisition process using the fast Fourier transform algorithm enables parallel correlation based on the circularity of code sequences. If a bit transition exists in the received signal sample, the correlation peak does not represent the maximum value at the true Doppler shift. Although there has been some research to solve the bit-transition problem, an analysis of this research with a performance index does not exist. This paper analyzes and compares calculation time and the signal detection probability of two existing methods and a new method for single-period code acquisition. Simulation results indicate that although the zero-padding method shows the best performance based on signal detection probability, the calculation time of the new method is the fastest of the test methods.
