An Algorithm for Improving DSSS Signal Carrier Wave Frequent Measurement Precision
Abstract
In terms of the large frequency-evaluating error using FFT algorithm,a kind of algorithm to enhance Doppler measurement precision of DSSS signal by using FFT evaluating peak value of frequency spectrum with assistance of DTFT is presented in this paper.Firstly,this algorithm evaluates the peak value and hypo-peak value of frequency spectrum via FFT.In order to get max-peak value and make sure the accurate position of frequency spectrum's peak value,this algorithm then performs DTFT using ten frequency values taken between their corresponding frequency values averagely.The simulation results demonstrate that it can enhance the precision of frequency in acquiring DSSS signal effectively.
