Paper Abstract

In this paper, the com bining impact of residual code phase and carrier frequency error on correlation is discussed in detail. And the correlation expression is given according to the code phase and carrier frequency estimate error. A code phase discrimination method and a carrier frequency discrimination method are proposed based on the discussion mentioned above. The analysis and simulation indicate that the proposed methods can restrain the impact of carrier frequency error on code discrimination within a small range, and the impact on frequency discrimination from residual code phase error is also limited to be lower. Tracking precision is improved obviously.
