摘要：

An algorithm for GPS receiver performing to mitigate cross correlations between multiple satellite signals is presented. By using the known pseudosequence, the cross-correlation between every two signals can be computed, whereas this cross correlation value often changes since Doppler frequency shift and code phase difference. With aim to estimate the correct cross-correlation, a synthetical factor was presented base on analysis of the characteristics of cross correlation under the influence of Doppler frequency difference and fractional code phase difference. Simulation result shows this scheme can mitigate the interference of 75%.
