Abstract

Abstract

The impact of residual code phase and carrier frequency estimate error on correlation is analyzed in detail, and the correlation expression is given. The advantage and deficiency of these existed code phase discrimination algorithms are analyzed from the view of the Linearity, the sensitivity for signal amplitude and carrier frequency estimate error, and the computational complexity. Based on the above research, a new C/A code phase discrimination algorithm is proposed. The analysis and simulation results indicate that the new algorithm which has good linearity can restrain the sensitivity for signal amplitude and carrier frequency estimate error and multipath error effectively, and has high tracking precision and low computational complexity. Tracking performance is improved obviously by using the proposed algorithm.
